Verifying display driver in control

I am trying to identify on a system which display driver is actively rendering.
you can have an intel driver and nvidia driver who are both loaded on the system and have both called DxgkInitialize but only 1 will be active at a time.
I have checked through https://docs.microsoft.com/en-us/windows-hardware/drivers/display/directx-graphics-kernel-subsystem
There seems no apis that can verify this?
