NVIDIA Tesla M10 shows memory in 0B

Hi

NVidia Tesla M10 32GB P2405-070 (Cisco P/N)
Running on Cisco UCS C240 M5SX, Firmware version 4.3(2.230270)
ESXi version 7.0.3 , 22348816 (Custom for Cisco UCS)
vGPU Driver 535.161.05

GPU is shown on CIMC
GPU is shown on ESXi but with memory 0 B

Tried both Shared and Direct Shared = Same Results = 0 Byte Memory

why?
