Yeah, you can turn it off mid-game but you can't turn it on again. The only option is restart a new game from scratch.You are right, I disabled it through the cheats menu on the phone. Silly me. The tutorial lied, you can indeed turn it off mid game. Reloading the game causes errors to show up afterwards. Weird.
IMO, this is just one of the many technically questionable choices of this game.

Currently I restarted the game from scratch with v1.002 and I didn't apply any mod. The only cheats that I used are disabling pubes growth and increasing lust.
I never cheated on anything else, not even on money.
I bet that nonetheless I will end up with something in the quest log that's impossibile to clear, as usual...
...like "talk to Fred" and when you click on Fred the only option is "I'll come back later"... ,
