Question : Supposing you have no Xserver running but you wish to take advantage

maybe not what you want and maybe of some usefullness...
In the xorg.conf you can put
Section "Device"
Identifier "Device0"
Driver "nvidia"
BusID "PCI:07:00:00"
Option "UseDisplayDevice" "none"
VendorName "NVIDIA Corporation"
EndSection
I always had to start an xserver (if you have more than 1 GPU you can add
device and screen sections has needed to xorg.conf). I've been using this
to render using Tesla cards.
Off course this needs to start X...
