As an administrator, Run the *.bat file to add the driver certificate as a trusted root certificate. (I'm getting reports that the bat might not work, run the command from an elevated command prompt from the extracted folder).

Don't install the inf. Open device manager, click on any device, then click on the "Action" menu and click "Add Legacy Hardware"

Select "Add hardware from a list (Advanced)" and then select Display adapters

Click "Have Disk..." and click the "Browse..." button. Navigate to the extracted files and select the inf file.

You are done! Go to display settings to customize the resolution of the additional displays. These displays show up in Oculus and should be able to be streamed from.

You can enable/disable the display adapter to toggle the monitors.
