You -> Gear icon -> Revanced Settings -> General -> Navigation Buttons -> Hide Shorts.

You need to also hide them from the feed and a few other places. You are not stupid; Revanced has too many options and the settings and large and confusing. It's easier to search "shorts" and toggle everything.

Thank you. I already had that setting enabled, but your comment inspired me to review all the settings again and I have been successful in hiding Shorts from view (for now, until Google changes something again no doubt).
