I don't know why everyone is fixated on the term incognito. I believe what GP wants (and me too) is to pause watching history or to at least exclude a viewing session from the recommendation algorithm.
The reason users such as yourself want this feature is because you don't have faith in the recommendation algorithm, right? If you watched a video and Google started pushing related videos that you don't want to constantly see, and you clicked on the "do not recommend this kind of video" option, and it actually worked, would you be satifised without this "exclude from recommendation algorithm" mode?
If yes, the better solution here would be to have a recommendation system that isn't garbage. I admit I kind of fancy this described mode, but the only reason is I don't currently trust Google to actually respect my expressed discontent. And if we don't trust Google to have a faithful recommendation system, why would we be willing to trust YouTube Premium?
