I haven't actually decided just to Disable Stories completely and if that works, then it's looks like you have get All or Nothing..
I have adoption disabled in neighborhood stories. Since downloading the new werewolf pack, sims have been adopting children despite the option being disabled.
I'm not sure if this is an issue with my CC or with the game itself. I've checked the broken mods thread and it looks like the ones I'm using have all been updated and cleared (I've also replaced them as needed on my end).
There's a thread about NS not turning off in the bug report forum here: https://answers.ea.com/t5/Bug-Reports/OPEN-Can-t-disable-Neighbourhood-Stories/m-p/11550809#M216181 If this sounds like your issue, you should click "me, too."
