Something like this?

\version "2.22.2"

\layout {
  \context {
    \Score
    \override Clef.font-size =
      #(lambda (grob)
         (let* ((glyph (ly:grob-property grob 'glyph-name))
                (is-change (string-endswith glyph "_change")))
           (if is-change
               0.5 ;; adjust
               0)))
    \override Clef.before-line-breaking =
      #(lambda (grob)
         ;; Necessary to trigger font-size callback.  Otherwise it is
         ;; not triggered because font-size is used via the same property
         ;; alist chain mechanism as markups.
         (ly:grob-property grob 'font-size))
  }
}

{
  \clef "treble"
  c''1
  \clef bass
  c1
}
