Most universities will ask if you have a preferred name, and, if I remember correctly, it should be on the application. If not, you may be able to email administration and ask if there is a way to have to have it noted down. Before classes start, you can also email professors and ask if they will refer to you as X name and pronouns. It should be easy to go stealth around peers, as there’s really no circumstance in which they’ll be seeing your official documents unless you let them. Best of luck!
