No, but she isn't male. If she is perceived as male, she might escape some of the female socialisation crap, but only as long as she is not recognised as female. If she is, she'll get crap for being gender non conforming in a way a man wouldn't be. Being female will be relevant.
How she presents and appears will also make no difference in issues such as abortion bans and maternity rights in the workplace.
Even if she came out as a transman and fully transitioned, she would still need to take hormones, with associated health risks for her female body, and have major surgeries with all the accompanying risks and side effects. Not something any non-transitioning man has to endure.
She's female and it's going to shape her life and impact her choices and experiences. How she identifies won't change that fact.
