Is it possible to obtain gpu memory junction temperature by Nvapi?

[nendonerd]

I'm using an rtx3090 card to mine eth, which is causing high vram temp. Programs like gpu-z and hwinfo implement the feature as "gpu memory junction temperature". And I'd like to get vram temp programatically, so I try digging nvapi. The closest stuff I found was NvAPI_GPU_GetThermalSettings(nvGPUHandle[id], NVAPI_THERMAL_TARGET_MEMORY, &thermalSettings);, but the result thermalSettings.sensor[0].currentTemp was 0x FFFF FFFF CCCC CCCC, which means the vram temp feature is not implemented? I've google A LOT and find ONLY this repo has implement some undocumented nvapi functions. Does any of these functions could get vram temp? I'm begging for your help.
