If you have to go outside of youtube you modify its behavior, that doesn't really qualify as "you can make it stop". That's like saying you can make someone stop shooting you by wearing a Kevlar vest.
Sadly not available when using the Apple TV to watch YouTube. If there's a NextDNS / PiHole method that stops YouTube ads, I could probably implement that...
Yeah they tweak the HTML enough that static stylesheet overrides can become outdated real quick. Very annoying. It's been a while since I looked, but there probably is some uBlock Origin filter list that'll handle this and will stay fairly up-to-date.
