Thanks for posting your question in the Microsoft Q&A forum.
Azure for Students subscriptions do not provide full access to Microsoft Entra ID features such as application registration or SSO configuration. This is a built‑in limitation of the subscription type and cannot be changed, even with role assignments. If you need these capabilities, you will need to use a different subscription, such as a Free Trial, Pay‑As‑You‑Go, or an organizational account provided by your school that includes Entra administrator access.
