Can I select OPENGL ?

I have Stable 2.0.7 server .. Nvidia Quadro card and Intel graphics card (in Intel i5-7500 cpu) .. I want to use intel graphics for display connection and Nvidia for Caspar .. There is Decklink for I/O .. After Caspar server start , it will select Intel OpenGL driver .. So it use intel graphics for caspar operations .. How can I tell caspar to use Nvidia OpenGL driver ?
