You be you.
Why would you answer a question falsely or deny who you are - thinking if you don’t, it will get you rejected? Anyone who doesn’t want you - doesn’t deserve you.
My guess is what will get you rejected is you don’t have the right academic profile, secondary profile (ECs/essays/LORs) for a given school. Not your gender.
But guess what, if your identity is what got you rejected and I find it highly unlikely, then good for you. Why go to an intolerant place.
You be you - and let your record speak for itself.
I’m Jewish. If a school rejected my kid for being Jewish, I’d be glad to know up front.
Except they would never know the why - and neither will you.
Your top schools all admit less than 5% of kids and you can be rest assured they turn down loads and loads and loads of qualified kids. Statistically, and I know nothing about your record, but I would most likely be correct that all three will turn you down - and you’ll never know the why - but I’m beyond confident, your identity won’t be the reason.
But work hard to achieve your goal. Don’t put up unnecessary and likely false walls.
Good luck.
