Every time you set a rocket without a satellite in it, you get a pop-up that you did that and the game pauses.

Is there a way to disable this pop-up?

Yes, i can change that in my personal game.

But can I do something in MY mod to disable that pop-up for everyone that installs my mod?
Or is creating a new scenario that is just freeplay without those lines the only way to do it?

That code is part of the freeplay scenario, so if a game with that scenario is started, this code will be executed. Maybe you could use an on_rocket_launched event handler that inserts a satellite into event.rocket if none exists and hope the scenario's handler is called after that. But the sanest solution would probably be to create a scenario without that code in it in the first place.
