Thank you for post!
I understand that you would like to make the changes of authorization policy via azure portal.
The policy at https://graph.microsoft.com/v1.0/policies/authorizationPolicy is not directly editable through the Azure portal. This policy is typically managed via Microsoft Graph API. If you need to make changes to this policy, you’ll typically use the Microsoft Graph API to do so.
Appreciate if you could share the feedback on this in our feedback community forum which is closely monitored by our product team.
