Hello, @zlschley and 
Welcome to the Canvas Community! The general instructions for editing your profile are detailed in How do I edit my profile in my user account as a student? . However, as the documentation notes, some schools have disabled certain functions within that feature, and that may well be the case at your university—which likely means the school manages students' names through a separate system.
I made the assumption based on your email address that you are attending UWM, and I found this page of contact links that you can use to request a change to the display name: Students | Canvas
Good luck with your courses!
