The second screen after you start the new name
And even if you load the save from a previous version, there are several choices during the event that allow you to bypass the ntr content.

Yea the disable netorare option definitely wasn't a thing last I was on , and if it was it didnt work at all cuz i still saw ntr content lol but good to know I might pick this back up , of course after it gets an update , whenever that may be
Edit:Jesus dude 2 months later and you add more ntr , you have ruined this gem my guy it was great before but now it's ntr garbage
Hinata is the one i was referring to then , (i imagine there's a whole lot more ntr now since i left but ill try with the ones i do remember, hinata , which all of her content is ntr and is not avoidable unless you just ignore her all together and then their is a sleepover scene with chojis fatass and ino, the ntr is also unavoidable with this unless you just don't activate the sleepover, and as far as avoiding the ntr best advice I can give is find another game lmao cuz anytime I supposedly had "ntr off" i still saw those scenes so I really don't believe Din when he says you can avoid it , again this game used to be the greatest but unfortunately Dinaki seems to be a cuck and would like us to be one along with him , hence the reason I know longer associate with this dumpster fire , but I do hope I was able to help you out in some way shape or form
