Since Princeton is SCEA, you can’t EA to another school, but you can certainly ED to another school. I would find another school to ED as well just to be on the ‘safe’ side.
Given your stats, ECs, and URM status, you are as viable a candidate for acceptance to Princeton as anyone. I want to say you’re ‘golden’ and likely in, but it’s Princeton. Keep doing what you have and you will have your choice of Top-10 college admissions.
