I can see both VRM temperatures read according to the files you posted.
With "GPU I2C via ADL" disabled, does it show other VRM #0 parameters, only the temperature is not shown ? Is it possible that some values are hidden ?
When I disable "I2C via ADL"from when i already enabled "I2C via ADL", all of other #0 parameters (CHiL/IR PMBus -GPU Core and CHiL/IR PMBus - GPU Aux) will gray.
After restarting HWiNFO (including reboot), other #0 parameters will disappear and #1 other parameters will show up.
I checked Layout page but no sensor is disabled.
