I missed it at first, but it's actually very easy in your example.

\version "2.24.0"

{
  \override Score.GraceSpacing.spacing-increment = 0
  \omit Staff.TimeSignature
  \repeat unfold 16 { \grace e'8 d'4 } \break
  \repeat unfold 8 { \grace e'8 d'4 }
}

\paper { indent = 0 }

The main caveat is that if you have a heterogeneous grace group like \grace { e'8 f'16 g'16 }, it will make all notes from the group spaced equally.
