How do I block Youtube entirely?

Hi, May I know how did You finally manage that? so far I've blocked several sides with RegEx and it's stopped playing videos, but it's still not perfect

Definitely works
Add these to regex
rr[0-9]+[-.]+sn-([a-z0-9]+).googlevideo(.com)?$
r[0-9]+[-.]+sn-([a-z0-9]+)
.googlevideo(.com)?$

You get only preview screens but no content and no ads. Actually I am trying to block ads but managed to block everything :joy::joy::joy::joy:
