Cyberpunk gets violent most of the time but you can play non-lethal often, i didn't finish it yet so i don't know exactly but i don't think this approach is rewarded.

Dishonored is probably the best you can get about this thing.

Generally a lot of games focused on stealth can give you the non-lethal approach, if you are into classic go Metal Gear Solid 3 Snake Eater, there even is a boss that you don't even need to shoot at to win.
