I don't think he will add an option to undo NTR if you are already on NTR path
If you don't want to use a walkthrough then just set NTR = off in setting
Nah man, even before on most NTR paths he gives always an ultimatum, and many players could not have known that stealing the soap could lead to NTR, so Chyos gives an heads up, no need to say to turn off NTR.
Example: You chose Lucius instead of Katherin, Lucius can’t do shit if you didn’t sell cum vials and even if you did you can pay her debt to solve the problem.
Or when you discover Henry true intention, you can kick him immediately out of the house, but only after some days he starts having sex with Penny.
Or the horrible traumatizing livestock for goblins in Bianca’s storyline, it gives you days before the horror starts.
Or Frisha even if you let her drink the wine, or give the kiss to Dave, you still have the last word to save her before going definetly into the NTR path.
Also some characters need the MC to continue their story and even when their NTR path is fully embraced you still have the option to get your girls back like Arianna and Kate.
You get NTR only when you fail battles (especially risky ones) or don’t pay attention to the dialogues and settings, some NTR paths that cannot be undone for now are some like Frisha or Dasan fuckery, and even then you get something that warns you.
