r.GraphicsAdapter doesn't work with plugin PixelStreaming in 4.27

I add r.GraphicsAdapter = 1 in my Engine.ini file,but when I start UE4 , I found the value of r.GraphicsAdapter has been changed, but not use the graphic card as my set. When i remove plugin PixelStreaming, it goes Ok. It did works when I Use UE4.26,but it does’nt work with 4.27.1 and also 4.27.2.
It seems select graphic card before I set the r.GraphicsAdapter value
