5 lines staff to 3 lines staff

Thank you @Christian_R !
So from what I see in your video there is no default option not to display staff labels (and I understand this of course).
Speaking in a more general sense, I was among the first users, years ago, to raise the question of the number of lines in a musical staff. I have since seen many other users working in contemporary music, and not only, pointing to this question.
You can find the original post here:

Today, the “Instrument definition window” covers part of this problem, but it is still limited. For example:

  1. lines can only be spaced one space apart;
  2. barlines cannot be set individually for each instrument.
