How do I boot to a NVIDIA GPU is it's secondary VGA in a system.

I have a system where a Maxtrox VGA is the primary display and the NVIDIA GT 730 card is secondary display. I have Linux installed along with the NVIDIA Linux driver.
I’m trying to boot Linux to the NVIDIA GT730 card but it always boots to the Matrox card.
Is there a way to force the Linux to boot to the NVIDIA GT730 card through the nvidia driver?
