I presume you mean beta, IV, or RV... Pretty much all screeners have some measure of past volatility that you can sort by.
stocks don’t have IV. options do.
Yup. The point is one measure of forward vol on a stock is the IV of an option on it.
I.e. my reinterpretation of his question was "how can I find stocks that will be volatile"?
Every option on a stock has a different IV.
Which is why you make composite indicators (or if lazy like me use someone else's).
A well known example not in the stock but index space would be VIX.
