Looks like Microsoft made a boo-boo in the preparation of the 20H2 image.
I did a test clean install on a couple of machines and noticed some hidden devices in Device Manager which are visible if you choose the Show Hidden Devices option. Looks to be virtual devices from a Gen 1 Hyper-V VM and a Xeon E5-2673v4 CPU. My guess is that this was the system they created the image on, and they sysprepped the image and never generalised it!
