Dell Command update and reboot

We have deployed Dell Command Update via Intune, customization included. DCU check if there is new updates each week and if there are new updates, it installs and request a restart. If I restart the computer via windows option, the updates are not fully implemented but if I restart using DCU option all work fine.

Is there any option or setting that I can apply to restart the computer from either of the 2 options work fine?

The problem is if the user don't restart from DCU when the deadline is reached, the computer restarts without warning.

Another configuration I would like to customise would be the notifications or warnings before the computer restarts.

Could you help me?

Best regards
