Good morning, @reynoldsn ...
Canvas administrators at your school can turn this option on/off, and it would apply to all users within your school's account...not for just a specific course or a specific set of users. Check out this Canvas administrator Guide:
How do I set details for an account? - Instructure Community (canvaslms.com)
Scroll down to about the middle of the Guide, and look for the heading "View Features". Then, look for the "User Avatars" checkbox (labeled as item 12) and the description of it below the screenshot.
If you are not a Canvas administrator, you would want to have a conversation with that person at your school...keeping in mind what I mentioned earlier that this would be a setting that applies to everyone at your school.
I hope this will help a bit. Let Community members know if you have any other questions about this...thanks!
