LIFE IN A VIRTUAL SPACE

Hi, any idea how I could possibly check this out on HW v10? For some reason creating a new VM from powercli is enabling DirectPath I/O on the network card and I can’t seem to get it disabled (The template is disabled) and can’t find .ExtensionData.UptCompatibilityEnabled. Any help is appreciated!
