Set signal line label visibility programatically

I built a script to rename a bunch of lines in a Simulink template model, however, now I'm facing the problem that by renaming them Matlab automatically activates showing the label of the signal line in the model. This is really ugly and hinders readability, so I would like to only show the label on those lines that have the label visible in the template model already before renaming.

Is there a way to determine/set the visibility of the signal line name in the model via a Matlab script? I've looked at the properties I can get from the line handle but couldn't find anything.

A signal line in a Simulink model, once it is named, it will always show. There is no property to hide or show it.

Unless, in your template model, it is shown as "<>" which means signal propagation. If the propagated signal names make it look busy, you can turn 'SignalPropagation' to be 'off'
