VirtualSMC and GPU temp

I have just got my hackintosh up and running pretty OK with OpenCore 0.5.9 and VirtualSMC (and plugins). I'm able to get info from most sensors but not GPU temp (HWMonitorSMC2). I did some search and seems it is NOT supposed to be available?

I'm thinking of falling back to FakeSMC just to get the GPU temp. I suppose I can just replace the kext and update the config file?
