The only solution is not to be online or move to the amazon like you just said. Even if you use google only as the search engine, they will still track it back to you. Also if you have multiple devices, it does not help to deactivate it on one device because as soon as you are doing anything on another of your devices, it will go right back.
For instance, I use YouTube Premium on two phones and thus I need to be logged in on Google and boom I get advertisement of specific things on TikTok on my other phone, even though I never searched for it on that device but "they" know it is me.
PS the "IP hiding" option is only for Safari, not for other apps like FB
