Hi @jmagro ...
It is possible that your school's local Canvas administrator(s) have chosen to not allow instructors/students to be able to change their name in your Canvas environment. This might be because your name is carried over from your school's SIS (Student Information System). You'd have to speak to your school's local Canvas admin or someone in your school's Online Learning/eLearning department to see if changing your name is a possibility. The Guides on how to do this in Canvas are:
I also found this Support page on your school's website: Student Help For Canvas | Distance Education.
I hope this information will be of help to you, Jacqueline. Please let Community members know if you have any other questions about this...thanks! Be well, and stay safe.
