I use a custom filters for uBlock Origin:
www.youtube.com##:matches-path(/)a#thumbnail[href*=“/shorts”]:upward(7)
www.youtube.com##:matches-path(/)a#endpoint[title*=“Shorts”]
Though they might need to be a little bit different depending on browser and OS (mine are chrome on mac).

YouTube Enhancer is one option but there are ones that are made just to remove shorts too.
