I've seen this too. I don't think you can find the option unless you keep swatting at the screen like a crazy person, so irritated at the ad that you're barely paying attention to the slightly dangerous act of fueling your vehicle. I think I've found it on every one I've used. I recall one having a mute that wasn't a proper mute, but instead would unmute itself after about 30 seconds, causing you to have to remute it. I think I screamed.
