Hello, this is a basic question. I know somewhere in NRAAS there is probably an option to turn off sims reacting to me whenever I enter their homes to repair items in the NRAAS repairman career. Does anyone know what the path is?

NRaas > Retuner > Settings > General > Social Interactions > Accuse of Impropriety

For future reference, googling NRAAS + the general gist of what feature you're in need of should usually direct you right to one of their own FAQs with all of those sorts of helpful tidbits (as it did for me and this, as I personally just use the Appropriately Inappropriate LTR when I need this functionality on a sim).
+ asking on their own forum might also get a speedier response, there's quite a few delightful active users.

Good luck!
