Question about placing RTX8000 GPU into WDDM mode

I’ve recently purchase RTX8000 48G GPU aiming to do Graphic Rendering. The OS is Redhat7.9 and Windows Server 2016. When I want to change the GPU from TCC mode into WDDM mode. Using “nvidia-smi.exe -dm 0” came up with a error " unable to set driver model for GPU 00000000:31:00.0 not supportd Treating as warning and moving on. All Done", I want to know if this GPU supported WDDM mode and the approaches to changing the mode.
