Hi,
Thank you for posting in Microsoft Q&A forum.
1,You can try to uninstall the SCCM client agent and delete the following registry keys:
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DeviceManageabilityCSP
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCMSetup
It will take some time to take effect, wait for a while.
2,You can also remove the computer objects from AAD and Intune, then re-enroll/resync to have a try.
Thanks for your time. Have a nice day!
Best regards,
Simon
