FriendlyName does not correctly identify a device in case of multi GPU hosts that have multiple identically named devices

[DavidFV2296190]

Both devices are identical but have different DevicePath. Relying only on FriendlyName will result in the script always partitioning the device that has the lowest device path; in this case ...0009 is always partitioned and the device with path ...0013 is never partitioned

This happens when someone has for example two RTX 4060's installed in their system? Do I see that right?

[DavidFV2296190]

Yes that is correct.

Nice find!
I think I would need to modify it so that you can still specify the friendly name, which should be sufficient for the majority of cases, but also allow the user to specify the specific device instance path to make it work in your mentioned edge case.
I will look into it, but currently I have not that much time, so please don't expect a fix too soon.
I also plan to update my release with another few improvements. I will add this fix to that upcoming release aswell.
