The article at Dell did state that the option to set the primary GPU had to be
there in the BIOS for it to be available to the control panel. So apparently
your Dell doesn't support it.
I've never checked to see if the option is there in ny Dell laptop's EUFI
settings.

When I use Hugin, it seems to only use the GPU for remapping images. That's a
much faster process than the blending that follows. I don't think blending uses
the GPU, it will use every available core on the CPU.

Doesn't the Nvidia control panel let you specify which GPU an app uses?
Assuming the control panel can SEE all installed GPUs.
Although that seems to be for specifying the GPU for *3d graphics*. If an
application isn't calling on 3d graphics functions, the application might not
be listed.
