Two graphical devices on the ESXi host.

The first of the graphical device has vGPU Mode set to "None"

The second of the graphical device has vGPU Mode set to "Mixed Size".

Modifying the graphical devices from "None" to "Mixed Size" would fail as the change made from GUI does not modify any settings.

For example:  nvidia-smi -q

Check that the configuration of the GPU card in the “PCI device” and “passthrough. And disable passthrough on the card then restart the server.

After ESXi is reconnected to the vCenter, the GPU card can be changed to “Mixed size” mode.
