You can use the ePO - On-prem server to view the Drive Encryption users assigned to the client system. The Drive Encryption software can be activated on a client system only after adding one or more users and enforcing the required encryption policies correctly.
You must have administrator rights to perform this task.
You can also remove users from a client system. Make sure that you have assigned the user at the system level or branch level. If a user is assigned at the branch level, the user is assigned to other client systems even after removing one system.

Click → → . The Encryption Users page lists the users for the selected system.
To remove a user:
