I am wondering if there could be more options added to NVEnc HEVC settings.
Specifically, disable SAO, psy-RDO, AQ, and I/B-frame controls.

'NVEnc HEVC' uses NVEncC which uses the NVIDIA SDK ( https://developer.nvidia.com/nvidia-video-codec-sdk) to access the onboard encoder chip of your NVIDIA card.
Calling 'NVEncC' shows the options NVEncC offers, anything that made sense to me (and is gpu based) of those options is exposed by Hybrid.
So unless both the SDK offer an option to support those things (ask NVIDIA) and rigaya supports them through NVEncC ( https://github.com/rigaya/NVEnc/tree/master/NVEncC) I can't offer those options inside Hybrid.
-> Nothing I can do about it.

Thanks for the response.
I cannot figure out the conditions for using AQ strength and temporal AQ are, they are disabled for me.
Weighted P frame is not in Hybrid. I noticed the issues in the github, but I think it should be included even without compatibility detection, since there are some who will be able to use it.

Hybrid disables options when they are not supported by the graphic card and driver combination (check 'NVEncC --check-features') or when another option is in conflict with them. For me GeForce GTX 980ti for example, I too can't use those options when encoding to H.265, but I can when encoding to H.264.
Here's the output I get from check-features:
