You can disable your watch history and then you only get related videos to the current video as far as I can tell. It does remove all of the videos from the home page, but I've been using youtube like this for 6 years and I don't mind it one bit. I have an alternate account with watch history enabled and I look at the home page every once in a while (obviously my history is very stale), it doesn't seem like anything of value was lost and I definitely never have to see a Mr. Beast thumbnail on my normal account.
