Thank you for posting this in Microsoft Q&A.
I understand you want to confirm whether transitioning to role-based access control (RBAC) has any effects on sponsorship credits or billing.
Changing user roles or permissions in Azure will not affect Sponsorship credits or billing. The Sponsorship program is a separate entity that provides credits to eligible users, and the credits are not tied to specific user roles or permissions.
