I can’t remember if this still works, but you used to be able to set the privacy of your profile photo to “only me”, which would prevent it from appearing in friends’ news feeds. After a few days or so you could safely set the privacy back to friends or public and be reasonably assured it wouldn’t be seen as its own post.
It is completely silly that you have to jump through these hoops, though, assuming it’s even still an option.
Btw, hiding something from your timeline has absolutely no effect on whether it appears in friends’ feeds or not. It’s purely about whether people can see if it they go to your timeline. Which is pretty unintuitive and anti-user: if I don’t want something in my timeline, why would I want it showing up in people’s news feeds?
