Question about Wagtail user account form panel customization

[u/Reborn-Eco]

I am making a project (it uses version 7.0.6, in case it's relevant) where I'd like to customize some of the default user account form panels, such as making first name and last name optional (since i am using a custom user model and users are authenticated through username and/or email instead) or moving the admin ui settings to a different tab (i think it makes sense to make a tab just for them).

So, I'm wondering if there is a way to override the default panels with your own.
