SOLVED!
I reinstalled the "Display Device" (AMD Radeon 6700M) in Device Manager that was giving me problems because there was no working Windows 11 driver and then removed it again and let Windows install the adapter as a "Basic Microsoft Adapter" and then disabled it. It appears Windows 11 needed to see the switchable graphics cards but only needs to use one. Hopefully that all made sense. Seems to be working as it did in Windows 10.
