Turn off "Flirt with [acquaintance]" wants?

I sometimes enjoy letting my Sim's wants dictate gameplay. But my Sim is now in a "romantic partnership" with her soulmate, which is heading towards a proposal and marriage. I've turned off the "exploring romantically" setting, but she still gets wants to "Flirt with [acquaintance]", which I don't want her to do. And these wants get in the way of other wants that I might want to act upon.

Yes, I can give her a potion to reset her wants, but short of that, is there anything I can do to turn off these "Flirt with [acquaintance]" wants? (Or any other type of wants that I don't want to act upon?)
