Probably not. GFN isn't meant for that.

That would be pointless.
This is how GFN works:
"GeForce NOW works on an opt-in model, which means that developers/publishers need to choose to have their games added to GeForce NOW through a supported store (e.g. Steam)."
It's always up to the game's devs/publishers to opt-in their games to GFN. If they aren't interested, it won't happen.
