Quadro M4000 GPU set OGL_DEFAULT_RENDERING_GPU environment variable

Hello !
I now need to set the value of the environment variable OGL_DEFAULT_RENDERING_GPU to: id,2.0:13F110DE,00000200,GL-(288,4,161,8192) @ (0)
Please tell me the specific meaning of each part of “id,2.0:13F110DE,00000200,GL-(288,4,161,8192) @ (0)” and how to obtain it through nvapi?
Thank you!
