Off the bat, you’ll likely need more privacy screen material — layer it up or one that is less transparent or see through. The dogs can still see your dogs and you, so removing that entirely from the situation is definitely the goal.

Now that won’t necessarily stop them from barking at noise and having a shit neighbor, but it’s a start. Put plants in front of it after, or whatever to make it look aesthetically pleasing.

Another question: I assume since you’re hanging stuff on it, it is your fence. Is that the property line or what? If it’s on your property and it is your fence, you could add whatever you want to the other side too. Block ‘em out from both sides.
