NVAPI / Frame buffer

Is it possible to do some kind of post-processing of the frame buffer through NVAPI?

I am looking to inject some effects to the graphics pipeline at the driver level without going through the CPU.
Ideally, I would like to apply some CUDA kernel to the frame buffer before is being shown.

Is NVAPI (NDA version) the right answer?
Thanks!
