Anyone know how to control the cellular settings in Windows10 Enterprise edition? (Registry question)

We have a few hundred Lenovo 460 laptops with cellular cards and it's a pain to have to manually enter the connection information as well as in some cases I'd like to be able to disable the cards when the laptops are being used for testing. My problem is I can't seem to find any real documentation on what registry settings would be used to do this via GPO since there doesn't seem to be any GPO templates for managing the cellular settings. I hope this isn't too basic of a question I've just run out of ideas and Google seems to have failed me.

This leads me to a more general question. How do you handle researching what registry keys go for what setting in Windows? Is there a website somewhere or methods you use?

**For anyone in the future, in order to control the APN or cellular settings you need to do it through the use of provisioning packages.**

**You'll need to download the Windows Configuration Designer and create your own custom provisioning packages. This is where the APN and other cellular settings for Windows 10 is located, not in GPO.**
