Can I mute greeting/farewell of NPC without muting all dialogue?

Yop all, need help to stop audio line of NPC from playing every time I click on them, accept a quest, turn in one or leave them ? I’ve searched for a while and the only thing I found was using the MuteSoundFile addon and after a few hour of muting individual sounds, I realised the massive work that this would be and my will was crushed. Is there any way to mute only greetings and farewell dialogue ? I’ve played this game for so long that I have to mute every NPC dialogue to stop the same four to ten line playing every time I want to repair stuff. It is not only for immersion but the repetition is killing me. I mean, the game itself is making a distinction between greetings and other type of dialogue so why can’t we mute them ?
