Become a non nude model - honestly this is all you can do. Don't use the same pics on your non sex work to sex work - do not use your real name or any part of your real name. This should make it harder for people to find you. Do not link accounts and make a separate email address for sex work.
I agree with
@Guy - but more on it, if anyone did find you or find out they would HAVE to be watching or looking for porn so why do you care? if your worried about people finding out then I would leave the industry now. Everyone will find out - when is the question. I decided to out myself before someone else did and I honestly think thats the best way to do it. I waited until I felt successful enough to tell my family/friends. If there not paying your bills then who cares? if it makes you happy then it should not matter. My sister disowned me, I cut off 2 toxic cousins and a toxic aunt due to them not being okay with my job. But guess what? there not paying my mortgage, my bills, and have 0 say in this. I'm a grown ass adult and so aren't you!
If you don't want to see them , don't search for them? if it's more of you not wanting to see them then thats really your only option.
