OpenGL doesn't have any way to do this except sometimes via vendor specific extensions. Basically how OpenGL works is it creates the graphics context on whichever device the system hands it. So you can configure the GPU used by OpenGL on the system level but not at the application level.

I don't remember being able to pick which card OpenGL uses, while with Vulkan it's a required question the App has to answer...
