Does this help?

%%%%
\version "2.20.0"

lineEnd = {
  \once \override BreathingSign.space-alist =
  #(grob-transformer 'space-alist
    (lambda (grob orig)
     (assoc-set! orig 'staff-bar '(minimum-space . 0))))
  \breathe
  \bar ""
}

\score {
  \relative f' {
    \key f \major
    \omit Score.TimeSignature
    \cadenzaOn
    f4 a2 bes4 c2 bes4 a2 g4 a2 \lineEnd
    a4 a2 g4 bes4( a) g4 f2( e4) f2 \lineEnd
    f4 a2 bes4 c2 bes4 a2 g4 a2 \lineEnd
  }
