How can I force the video group user to call only the 'iDH' driver instead of the root account?

Hello?

Installed with reference to Intel documentation and use GPU supported main board.

If the CreateVAAPIDevice() function is called more than once in a process
va_getDriverName() results are different for root account and video group user
Is there a way to force the video group user to call only the iHD driver?

Thank you..
