Using the Graph API to enroll hardware tokens is a newly introduced feature in Entra ID. Currently, you can use the Graph API to upload tokens to Entra ID, but there is no UI in the Entra Admin Portal for administrators or the help desk team to manage those tokens. Those tokens can only be self-enrolled by the users.
