Can you jam an FM radio signal with a FZ?

Let’s say, hypothetically, there’s a guy who parks on your street once a week and – for some reason that no one understands and he refuses to explain – he absolutely BLASTS a butt rock radio station from his car speakers for 20 minutes at a time, so loud that it bounces off all the buildings on your narrow street and it sounds like it’s coming from every single window. And when you go out and say, “Hey dude, I’m taking a call for work, could you not do that here? Or anywhere, really?” he smirks and looks at you like you’re the one acting crazy.

Again, this is a hypothetical.

But in this hypothetical situation, could you use a FZ to jam his car radio? How? (I know that many people might call the police/311 and ask them to do something about this. That is not how I want to do this.)

Thank you for indulging this completely made up scenario.
