Remove selected unremovable MDM profiles on macOS Ventura

The MDM maybe removed but the Serial Number of this computer is Still Registered with the MDM Service

At any time, the MDM Service can again Remotely take Control of this computer and possible reinstall their Service

Until such time as the Serial Number is removed from the MDM, this computer can be Controlled by them at any time

It is possible to delete unremovable MDM's in recovery mode by disabling SIP (System Integrity Protection) in the terminal.

Sadly, no. Only the MDM administrator can do that by removing that Mac's serial number from their profile.

I think you should contact the owner (the school) and have them remove the profiles.

I've found an old school laptop and it's got a few MDM profiles on it, I want to remove one of the MDM profiles on it but not the others. Unfortunately the remove button is greyed out. If found ways to remove all of the MDM's via recovery mode, however I only want to remove the single profile, and I don't know how.

You can not remove any MDM profiles unless you are the owner of the computer who installed the MDM profiles. Recovery mode will not remove the MDM profiles.

Do not attempt to circumvent the security of someone else's device. It will only end badly.
