No, it doesn't.

The exported Symbol you're talking about - just does one single thing:
- when more than one GPU is installed on a given system...
- it will ignore the "usual default-GPU" (mostly a less powerhungry integrated GPU from Intel)
- and instead forces the executable to "switch to the NVidia-Chip" (and Drivers) at startup

And it does that switchery on "all Values behind the exported Symbol-Pointer",
which are different from Zero (an explicit value of 1 is not the only Value which works).
