Yes I do t like that either and sort of want it too for some channels
so what I do is use YouTube revanced with login , I purge my history once three months , and start a random video for first time like may be a documentary or a really.old/new song and then it germinates very different things for me from there on. And I got no ads at all. :)
Hello, I would be greatful if I can do what you said I can do.
I strongly hope and wish you feel better.
