How to make cloth brush aware of other model? (collisions or something)

I’m trying to do wrinkles and folds for cloth on character, but there’s no way to make collisions, so sculpt gets through character model, and half (or quarter) of my time i spend just to get cloth out of character and still make it look decent. Is there anything i can do automate this process?

I saw that 2.9 have this feature (collisions for cloth brush/filter), but i couldn’t activate it
