Windows 10 Home 64bit 20H2 Intel(R) Serial Driver Issues

Has anyone gotten Windows 10 Home Edition x64 20H2 working with the published drivers for -

Intel(R) Sideband Fabric Device
Intel(R) Serial IO SPI Controller
Intel(R) Serial IO UART Controller

I keep getting errors of the form -

Windows encountered a problem installing the drivers for your device
Windows found drivers for your device but encountered an error while attempting to install them.
    Intel(R) Serial IO UART Controller
A problem was encountered while attempting to add the driver to the store.

Any ideas?

Try to turn on testsigning on your system under test:

bcdedit /set testsigning on

Then retry the installation.

I just do the basic driver installs for the Rock Pi X and then do the updates in 20H2. I get them to install when I do Windows 10 update and check the driver updates. They install after that.
