I don’t recall an option on YouTube to delist a video from search but still have it be accessible from a channel. It’s either publicly searchable (public) or it’s only viewable with a link (unlisted) or completely private (private). The ones viewable with a link will not appear anywhere but this video does appear on the channel. So clearly there is a fourth option youtube has behind the scenes.
