Togle off track volume line

How do I togle off the track volume line

When I’m using the in track volume line (or pan line or aux out line), I can’t figure out how to togle off the line.
I need to save and close n_Track for that.
Does anyone has a clue ???

yes, this got me at first - just select the “select” arrow two icons right from the “volume” symbol

Thank you, I’ll try it.
