You could use a service like Power Automate to run an API call to Jamf to push the restart MDM command on a schedule.

Thank you, we are going to see if this available with our Microsoft Bundle. Are there any free or other options?

The other option would be to look into JAWA https://github.com/jamf/JAWA. Technically free, but obviously you have to factor in the cost of infrastructure.

The remote schedule feature is not yet available, but you can use this feature:
1. Create a Smart Group or static Group, named Apple TV
2. View (bottom menu)
3. Action
4. Send Remote Commands
5. Restart Device (iOS 10.3 or later, or tvOS 10.2 or later, supervised)
You can do it periodically, every month or according to your wishes.
