Conceal carry while in uniform OFF POST.

I am a 25yo Army veteran going through an Army ROTC program in Texas to go back in commissioned. Recently our command team as made it a policy that we cadets have to wear our uniform for all university classes in the name of program pride. We have had a shooting on our campus before. Some of my bigger classes (80+ students) only have 2 doors to get in and out. This kind of setting stress me out. I have my LTC and routinely carry when in civs. Is there anything I can bring to the command team here on campus to have them reverse the uniform policy or any regulation that states you can cancel carry while off post in uniform? While I am technically a civilian, I understand that carrying of a firearm in uniform is heavily regulated and have no idea where to look.
