i think linkedin in general is stupid but there isn’t rly much u can do to hide your background. if u really think it’s a big detriment to your job search don’t upload a profile picture and use a nickname but otherwise i wouldn’t suggest hiding it bc no profile pic is worse than being seen as “ethnic.” more often that not u aren’t applying to a job through linkedin so it shouldn’t be a problem. just make sure ur profile is articulate and u should be ok
