Hi.
All vendors' MDM solutions provide management of only MDM payloads supported by Apple.
Apple does not provide any MDM Payload related to power management of iOS devices.
The same goes for MDM Payload on Mac as well as iOS.

Still, I checked the 'Apple Configurator' in case I was wondering, but likewise, I couldn't see the functions of power management.
It seems difficult whether Apple will add this payload.
