Doesn't sound like it. Enoch was included by Catholics, not Jews, ever.
It's in the Torah and Talmud and other Ancient Jewish Writings.
It's still in Oral Tradition but written all throughout the True Hebrew Old Testament.
So, what do you mean, they don't have it?
It is literally Everywhere and I quoted from Leviticus of it with connection to God, Moses.
From Book of Enoch:
Azazel is
the rebellious angel at the head of a heavenly plot to take over the earth. The First Book of Enoch retells the story cited in Genesis (6, 1–4) of the angels who had relations with the daughters of men. The offspring of their unnatural union were the nefilim—giants of renown who filled the earth.
From the Torah/the LAW:
Azazel is
one of the leaders of the rebellious Watchers in the time preceding the Flood; he taught men the art of warfare, of making swords, knives, shields, and coats of mail, and taught women the art of deception by ornamenting the body, dyeing the hair, and painting the face and the eyebrows, and also revealed .
And here are some Verses with God addressing Moses about
AZAZEL:
Leviticus 16:
8 and he shall place lots upon the two goats, one marked for יהוה and the other marked for
Azazel.
9 Aaron shall bring forward the goat designated by lot for יהוה, which he is to offer as a sin offering;
10 while the goat designated by lot for
Azazel shall be left standing alive before יהוה, to make expiation with it and to send it off to the wilderness for
Azazel.
