Is there a graph where you can see the skews?
In reality, even if you have a graph which is an average across maturities, you wont see the one strike which has a spike on large volume/open interest because some hedge fund decided they want to own that strike/maturity.
It's tedious to look across the strikes and maturity to look for unusual bid/ask spreads but that is where the gold hides. It's not actually where the big volume is being done but usually where there is no volume and the market maker is willing to offer or bid the options. So you want the implied vols on the bid/ask.
As retail traders, we have the advantage of doing smaller size so the market makers bid/offer may be all we want to do via a hedge fund that needs to trade 1,000 contracts+. Where there is no volume, get your fill and don't go back to those clowns, just trade in the stock/product to unwind later. If you trade small so your not squeezed and the market goes in your favor, your position delta becomes too big for these guys anyways and they don't want to trade with you.
