Probably can’t tbh.
Your location data, where you connect to online, any wifi you are near or connect to, your mobile data, any social platforms you connect to, any phone number that might be in someone else’s contacts for you, will produce enough data to infer who you are and give it away.
Dark profiles, ie what you don’t see going on in the background, constructed by mapping network graphs across multiple sources are extremely effective.
On a practical level, on some platforms you could preemptively block people from seeing you.
