Undo your fog lights' wiring. Ground them to chassis if they aren't already. Rewire them independent of the car's factory wiring.
ground (–) ---- light --------------- generic on/off switch ---- fuse/fuse holder ---- battery (+)
In some cars you could pull the fog light relay and create a jumper to make it possible to use factory switch to turn on the fog independently of the headlights. I am not familiar with how the Versa is wired and don't see any need to have just the fog lights on, but the above is probably the easiest brute force way to achieve it.
