I really hate it when people don't even _try_ entering a single note
themselves and leave all the work to every single reader.

That being said, you could use something like

visibleAfter =
#(define-music-function (n mus) (index? ly:music?)
  #{
    \set Staff.countPercentRepeats = ##t
    \set Staff.repeatCountVisibility =
    #(lambda (cur ctx) (>= cur n))
    #mus
    \unset Staff.repeatCountVisibility
    \unset Staff.countPercentRepeats
  #})


\new Staff
{
  \time 6/8
  << \visibleAfter 4 \repeat percent 4 { <d'' g''>8[ r q] q[ r q] }
     { \skip 8*6*3 <>\< \skip 8*6 <>\! }
  >>
}
