HI there! You can’t disable it, but you can change it to any existing user role you have on your site. Just go to “Donations > Settings > Advanced” and update the “Default User Role” setting.
See our docs on that here:

Thanks!
Actually… just noticed you already linked to that doc, so perhaps I misunderstand what you need. If you don’t want users to be generated at all, then in the Form Edit screen you need to set the “Form Display > Registration” option to “None”. See docs on that here:
https://givewp.com/documentation/core/give-forms/form-display/
If I still misunderstand, then please clarify so we can help further.
