Developing Device Driver: What is "Windows Debug Policy" for ARM processor?

What is "Windows Debug Policy"?

The documentation for "Provision a computer for driver deployment and testing (WDK 10)" says:

"If the target computer uses an ARM processor, install the Windows Debug Policy. This can be done only by Microsoft or the manufacturer of the target computer. "

My Windows 10 computer has a ARM processor. How can I determine if it has this "Windows Debug Policy" installed?

Does this mean I can't develop a device driver on a Windows 10 computer which has a ARM processor?

When testing a device driver, do both the target computer and host computer need to have the same Windows operating system version? I have a Windows 10 and a Windows 7 computer.
