Yup, no option on desktop either. This is obviously not based on viewing history, YouTube is doing something weird just with the recommendations embedded into search results.

For me these "you also might like" sections in search results are 50 woodworking and 50 gross out garbage.

It's nice to know my misery has company.

It's nice to know that as poorly as I think of Youtube, that's still a significant overestimation...
