Any way that setting could be toggled via a dialog trigger? I don't see one in any documentation I have unfortunately.
Not as a vanilla thing.
@Pim_gd could conceivably add it to the
dialogueActions mod, but I'd consider it a
misfeature.
I think that the contents of the "Options" tab should be at the player's discretion, because they
persist between gameplay sessions. I would consider it inappropriate for a mod (or a dialogue file) to veto one of the user's decisions. For example: a breathplay scenario won't work properly unless the user has enabled the "Breathing" option. It would be reasonable for a mod to
check this setting during initialization, and to
warn the user if a prerequisite feature is disabled. To directly toggle the setting without the user's knowledge (or consent) would be somewhat shady.
