Is it worth it to pass as my preferred gender at UT orientation?

I’m a 18 FTM that’s about to attend their freshman orientation this month looking for advice from other trans students. I’ve been debating whether it’s worth it to try to go by he/him at my orientation or not. I haven’t physically transitioned and won’t be able to any time soon, I do have a binder but a rather feminine voice and no packer. I’m wondering if it’s worth it since if I go by he/him, I’d also have to somehow explain why I’m being put in the girls dorm for the night. Im also thinking if I don’t go by he/him, If to go by they/them so I at least don’t have to be called by assigned gender. I wanted to ask for advice from anyone who tried passing as their preferred gender at orientation.
