Is it possible to adjust colors via ppeffect or something similar that also affects NV? I am trying to tone down the green and make it more of a greyish NV. However switching on NV seems to override any color adjustments using modules.

No I don't think that is possible. If I'm wrong, I would be interested in learning how to access it.
