Not according to Numbers 15:

“Thus it shall be done for each bull or ram, or for each lamb or young goat. As many as you offer, so shall you do with each one, as many as there are. Every native Israelite shall do these things in this way, in offering a food offering, with a pleasing aroma to the Lord. And if a stranger is sojourning with you, or anyone is living permanently among you, and he wishes to offer a food offering, with a pleasing aroma to the Lord, he shall do as you do. For the assembly, there shall be one statute for you and for the stranger who sojourns with you, a statute forever throughout your generations. You and the sojourner shall be alike before the Lord. One law and one rule shall be for you and for the stranger who sojourns with you.”

The Lord spoke to Moses, saying, “Speak to the people of Israel and say to them, When you come into the land to which I bring you and when you eat of the bread of the land, you shall present a contribution to the Lord. Of the first of your dough you shall present a loaf as a contribution; like a contribution from the threshing floor, so shall you present it. Some of the first of your dough you shall give to the Lord as a contribution throughout your generations.

“But if you sin unintentionally, and do not observe all these commandments that the Lord has spoken to Moses, all that the Lord has commanded you by Moses, from the day that the Lord gave commandment, and onward throughout your generations, then if it was done unintentionally without the knowledge of the congregation, all the congregation shall offer one bull from the herd for a burnt offering, a pleasing aroma to the Lord, with its grain offering and its drink offering, according to the rule, and one male goat for a sin offering. And the priest shall make atonement for all the congregation of the people of Israel, and they shall be forgiven, because it was a mistake, and they have brought their offering, a food offering to the Lord, and their sin offering before the Lord for their mistake. And all the congregation of the people of Israel shall be forgiven, and the stranger who sojourns among them, because the whole population was involved in the mistake.

“If one person sins unintentionally, he shall offer a female goat a year old for a sin offering. And the priest shall make atonement before the Lord for the person who makes a mistake, when he sins unintentionally, to make atonement for him, and he shall be forgiven. You shall have one law for him who does anything unintentionally, for him who is native among the people of Israel and for the stranger who sojourns among them. But the person who does anything with a high hand, whether he is native or a sojourner, reviles the Lord, and that person shall be cut off from among his people. Because he has despised the word of the Lord and has broken his commandment, that person shall be utterly cut off; his iniquity shall be on him.”

Note also Leviticus 22:

And the LORD spoke to Moses, saying, “Speak to Aaron and his sons and all the people of Israel and say to them, When any one of the house of Israel or of the sojourners in Israel presents a burnt offering as his offering, for any of their vows or freewill offerings that they offer to the Lord, if it is to be accepted for you it shall be a male without blemish, of the bulls or the sheep or the goats.

Thus, god fearing Gentiles were expected to worship at the central Sanctuary.  From Psalm 118 we see an appeal to Israelites, Aaronic priests, and god-fearing Gentiles:

Let Israel say,
“His steadfast love endures forever.”
Let the house of Aaron say,
“His steadfast love endures forever.”
Let those who fear the LORD say
“His steadfast love endures forever.”

Likewise, Psalm 115:

O Israel, trust in the LORD!
He is their help and their shield.
O house of Aaron, trust in the LORD!
He is their help and their shield.
You who fear the LORD, trust in the LORD!
He is their help and their shield.

The LORDhas remembered us; he will bless us;
he will bless the house of Israel;
he will bless the house of Aaron;
he will bless those who fear the LORD,
both the small and the great.

And then Psalm 135 does the same thing, but distinguishes Levites as another group:

O house of Israel, bless the LORD!
O house of Aaron, bless the LORD!
O house of Levi, bless the LORD!
You who fear the LORD, bless the LORD!
Blessed be the LORDfrom Zion,
he who dwells in Jerusalem!
Praise the LORD!

Compare this terminology to what we find in Acts 13:

Now Paul and his companions set sail from Paphos and came to Perga in Pamphylia. And John left them and returned to Jerusalem, but they went on from Perga and came to Antioch in Pisidia. And on the Sabbath day they went into the synagogue and sat down. After the reading from the Law and the Prophets, the rulers of the synagogue sent a message to them, saying, “Brothers, if you have any word of encouragement for the people, say it.” So Paul stood up, and motioning with his hand said: “Men of Israel and you who fear God, listen….

“Brothers, sons of the family of Abraham, and those among you who fear God, to us has been sent the message of this salvation….”

And if there were still any doubt, the response to the message erases it:

The next Sabbath almost the whole city gathered to hear the word of the Lord. But when the Jews saw the crowds, they were filled with jealousy and began to contradict what was spoken by Paul, reviling him. And Paul and Barnabas spoke out boldly, saying, “It was necessary that the word of God be spoken first to you. Since you thrust it aside and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles. For so the Lord has commanded us, saying,

“‘I have made you a light for the Gentiles,
that you may bring salvation to the ends of the earth.’”

And when the Gentiles heard this, they began rejoicing and glorifying the word of the Lord, and as many as were appointed to eternal life believed. And the word of the Lord was spreading throughout the whole region. But the Jews incited the devout women of high standing and the leading men of the city, stirred up persecution against Paul and Barnabas, and drove them out of their district. But they shook off the dust from their feet against them and went to Iconium. And the disciples were filled with joy and with the Holy Spirit.

The audience is made up of Jews and God-fearing Gentiles who are addressed as those “who fear God.”

Thus Paul can argue from the principle as undeniable, “Or is God the God of Jews only? Is he not the God of Gentiles also? Yes, of Gentiles also, since God is one..”
