remove extra line in outside staff notes

[Cordelia]

Hello,

is it possible to remove the outside staff lines notes in a "\override 
StaffSymbol.line-count =  #1"?
Thank you,
Cordelia



e.g.

\layout {
  \context {
    \Staff
    \override StaffSymbol.line-count =  #1
  }
}
\score {
  \relative c'' {
    c5\( f\)
  }
}
