In seasons 3 v0.4.5 in the "mute individually" menu, after all character names that can be muted, last option is "Inceton": since I tested it hoping it would have muted the moaning on each menu click but didn't disabled it, I guess it could mute the narrator, but I haven't tested it; just guessing.
Besides, I don't know if in Season 1 "Inceton" is one entry of the "mute individually" menu, but you could give it a try.
Or maybe substitute them with silent audio files having the same name?
Deleting them from the folder without deleting each reference in the code might cause "file not found" errors, maybe?
