SSAO put to 4 increases stealth vision.
When put to 6 and 8 they become a lot harder to see without NV.

What info have you got?
Banned console commands are greeted warmly.

i only user superclear nanovision ..
put these in your game.cfg file
r_NightVisionBrightLevel = 0
r_NightVisionCamMovNoiseAmount = 0
r_NightVisionCamMovNoiseBlendSpeed = 0
got it from a youtube user
this makes your NV clearer, that means it isnt blurred or something and i think you can spot enemys a little bit better with that .. try it yourself

Isn't this borderline hacking?

Lower the quality. Run on high, disable SSAO, PostMSAA, Colograding, HDR bloom, motionblur, etc. Jack the brightness up to 100%, and then seeing people in stealth when they're within their respective distance is easy.

Can I see screenshots to compare?

SSAO goes to 3 and 0 only when shading set to extreme or ultra. On other setting that high, very high SSAO setted to 4 by game settings.

The main facts that this methods that other console commands can be changed by human and even in game, If there are something that disturbs player. And this methods of setting up your client for yourself is not hacking. It's only will create a difference for those who playing without it and with it. But nobody mentioned that who plays without it can't do the same. So if they like that method of settings for client they can use this also for comfortable play. It's like don't try to set up all world for you.

Hacking is only when you're using soft that is not the game formally approved. Like cheats that's not included in game.(speedhacking, wallhacking, aimbotting, and etc).
And hacking it's when you hacking stats of the profile in game (EXp, dogtags, kills, etc)

Hacking is when you're forcing, with other soft, client to act not as it can act in normal, without other soft. So if you're not using any unofficial soft for hacking, there is no hacking.

Back when they allowed really high FoV values I'd say that's cheating too because it's like having eyes on the back of your head

You're editing the settings of the client to give yourself an advantage. That you're not using memory injection to do so just makes you a noob.
