My bad, I was not supplying the environment variable in the correct way. It is working via mpiexec now

```auto
/opt/ParaView-5.10.1-egl-MPI-Linux-Python3.9-x86_64/bin/mpiexec \
     -env VTK_DEFAULT_EGL_DEVICE_INDEX=0 /opt/ParaView-5.10.1-egl-MPI-Linux-Python3.9-x86_64/bin/pvserver : \
     -env VTK_DEFAULT_EGL_DEVICE_INDEX=1 /opt/ParaView-5.10.1-egl-MPI-Linux-Python3.9-x86_64/bin/pvserver

```

```auto
