Howling Abyss Shopkeepers

Came back after some years away, started messing around in Howling Abyss again. Years. Still looking for a way to mute the shopkeepers, if anyone has found a secret? I assume not, as google had no links or solutions.. Especially the bot side keeper, so tired of hearing "FIGHTING'S A LOT MORE INTERESTING THAN SHOPPING, YOU KNOW" the instant I respawn. And their long ass monologues. Just let me have some peace and play, lol.
