Delete mobile device management (MDM) servers
In Apple Business Manager , sign in with an account that has the role of Administrator or Device Enrollment Manager.
Tap Settings at the bottom of the sidebar, select your MDM server under the MDM Server list, then tap Edit.
Tap , then do one of the following:
Select the MDM server that the devices will be reassigned to, then tap Reassign & Delete.
