I'd recommend using \temporary\override in to mimic \once behaviour more 
closely:

\version "2.23.5"

\layout {
  \override DoublePercentRepeat.slope = 2
}

{
  \repeat percent 2 { e'2 e' e' e' }
  \override DoublePercentRepeat.slope = #.3
  \repeat percent 2 { e'2 e' e' e' }
  \revert DoublePercentRepeat.slope
  \repeat percent 2 { e'2 e' e' e' }
}

{
  \repeat percent 2 { e'2 e' e' e' }
  \temporary\override DoublePercentRepeat.slope = #.3
  \repeat percent 2 { e'2 e' e' e' }
  \revert DoublePercentRepeat.slope
  \repeat percent 2 { e'2 e' e' e' }
}
