Normally you can press one of the buttons to turn those off. The mute button is unlabeled, of course, but in my experience every one of these I’ve come across can be muted. Annoying as fuck in principle, no doubt.

Edit: you were talking about the display, not noise. Leaving this here anyway in case someone else didn’t know they can be muted

Luckily that's still uncommon here, so there's only a couple gas stations that do it. I won't give them a cent.

Turning off TVs with adds has been the only usage I've been getting out of my Flipper zero. Doesn't work always, but I did have some success and I'll always try whenever I have to spend time longer time anywhere.
