MDM ScheduleOSUpdateCommand does not install an update

Hi, I tried to install an update via MDM on several BigSur (macOS 11.01) devices and most of the time it fails.

Sometimes the update is downloaded correctly but the device never install it and the device does not restart at the end, even when sending the option: InstallForceRestart.

Please, I would appreciate any help. (Apple Feedback ID: FB8949381)

Thank you.
