Have you considered a platform like freetube that allows you to fully block shorts?
I’ve been using it for ages now (desktop application, I use it on Linux, works great), but other platforms for watching YouTube without ads are also likely to have “distraction-free” mode where all that obnoxious shit gets blocked or turned off, like when I view a creator I’m subscribed to the -only- thing that comes up are full-length videos. No community page, no shorts, no playlists and follows, nothing but videos which is what I’m there for.
You also get the perk of blocking ads and sponsored segments, self promotion, etc. so very nice to use.

If you want to remove them, you could use something like the unhook.app extension. I only know about it because Pewdiepie linked to it in a recent video, so your milage may vary, but I do know it supports removing shorts entirely.
