Unfortunately, I don't think this is possible without editing the addon.
This is entirely the fault of addonmakers, who (IMO) could and should ALWAYS provide a means to disable "extra" stuff that the editor may not want in his mission.
I personally can't stand having an extra, worthless action in my menu like "lower goggles", or "put on helmet", or the millions of other worthless actions that addonmakers love to make for some reason... [/angry rant]
