GPU not found error occured in PixelStreaming plugin of Unreal Engine5

I facing problemd GPU not found error occured in PixelStreaming plugin of Unreal Engine5.
My environment is follows,

  • PC: AWS g4ad instance
  • CPU: AMD EPYC 7R32
  • GPU: AMD Radeon Pro V520 MX
  • OS: Windows Server 2019
  • Instance: g4ad

I know pixelstreaing in AMD GPU needs AMF encoder, and found g4ad instance enable amf encoder on driver install document of aws.
So, I installed AMD driver software version 27.20.11025.4019 from AWS.
