How to block "Personal Hotspot (Tethering)"?

Hello,

I want to block or deactivate the "personal hotspot" function on iPad or iPhone. We want to disallow the use of this function for all of our users.

I checked the "Apple Configurator" and also our MDM solution. It is not possible to block. Also our phone provider is not able to deactivate this function.

Is it possible to send a "mobileconfig"-File or a "IPCC"-File to the device? Someone has an idea?

Many Thanks

Tobias
