This is what I did for this, based on the standard template for custom inventory. If I recall the INTEL-SA-00075-console.exe command creates the registry entries which can then be collected:
const HKLM = &H80000002
strComputer = "."
strKeyPath = "SOFTWARE\Intel\Setup and Configuration Software\INTEL-SA-00075 Discovery Tool\ME Firmware Information"
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")
strCommand = "INTEL-SA-00075-console.exe -c"
execCommand strCommand

nse.To = "{1592B913-72F3-4C36-91D2-D4EDA21D2F96}"
nse.Priority = 1
