There's not an option to disable NTR that I've come across, where do I find it?
And also there's no way to start a game straight from the update
for the ntr, depending on who you ask, there is no ntr, because they dont show it on the screen, as for your second question,
what are you talking about? there is, the problem is that, that option is called new game, because this update was all about remaking the story, so to see the "new content" you gotta play from the start, as that's the new content.
now if you ask me if it was worth 6-8 months of nothing for it, i gotta be honest and yell from the bottom of my heart a massive "Darth Vader shattering the surgery room" no.
