Display mode Sector tool not running in Windows Server 2022

Dell R7725 running dual RTX 6000 Blackwell Server Edition.

Need to sent / change the Mode to WDDM

When running .\displaymodeselector.exe --gpumode we get no output, just a returns to C:

Same when trying

.\displaymodeselector.exe –listgpumodes

.\displaymodeselector.exe –list

(power sell does the same)

Also tried nvisia-smi -fdm 0

Driver Version

595.97-data-center-tesla-desktop-winserver-2022-2025-dch-international

Cards are in TCC mode

Any ideas ??
