How is this "nightly reboot" accomplished?
In Windows 10, you want to go to Setup -> System -> Projecting to this PC and make sure that this feature is disabled. You also want to go to Setup -> Devices -> Bluetooth & Other Devices and either disable Bluetooth completely or go to Setup -> Devices -> Bluetooth & Other Devices -> More Bluetooth Options and either disable discovery or enable notifications (to ensure it doesn't use Bluetooth connection until you say-so).
Hope this helps,
turning off Bluetooth seems to have worked, I use a hardwire keyboard so I am good to go.
