Lock or unlock Personal Hostspot option

As of late we are experiencing the "Personal Hotspot" being activated without user intervention. Our carrier is unable to restrict this on the iPad, and instructed us to reach out to a third party (e.g. SimpleMDM), The solution appears to be to monitor the state of the “Personal Hotspot” and automatically turn it off through MDM whenever it is activated.
