I turn off watch history entirely
It nags you to turn it back on and completely disables the homepage recommended/popular feed but I’ve grown to like it a lot. I still go through my subscriptions tab to find stuff to watch, and I still get related videos on individual videos that I watch that I can hop to if I want to explore outside that bubble of existing subscriptions. It’s like going back to 2014 youtube or whenever they started making the homepage purely algorithmic
