Remove Required Information

I’d like to remove the first name/last name/email section to make the donation process as simple as possible. Is there a way I can stop requiring that information for the button to proceed?

I can see the php that sets the information to require but I can’t locate it in the coding and I’m not sure if I’ll need to change code in multiple locations when I do find it.

I’ll keep tinkering around until then and see what I can come up with. Thanks!
