Use of NVWMI with no outputs connected to a display

Hi, We’re trying to create a robust interface to the ‘fakeEDIDonPort’ property (surveillance video wall product). However, if no outputs are connected, WMI returns the fact that the system has no GPUs to manage. This is true for any NVWMI property calls. PowerShell or Program calls (
The NVIDIA control panel also reflects this functionality… how strange.

Rhetorical questions:
What if you want to read the GPU temperature via WMI? we have to plug a cable in?
what about data-mining use cases? I’m sure(hope) we are missing something here.
If you connect a cable to any output, you then get access to all the other disconnected outputs!

How can we make a call to set a fake edid file when the user has no cables connected?
