The magic incantation would be \tweak vertical-skylines ##f.


\version "2.22.2"

rightHand = {
  e'2
}

leftHand = \relative {
  \clef bass
  <<
    {
      \slashedGrace {
        e8
        \tweak positions #'(-4.5 . 10)
        \tweak extra-spacing-width #'(-1 . 0)
        \tweak X-offset -1
        \tweak vertical-skylines ##f
        \arpeggio
      }
      <e gis>2
    }
    \\
    {
      <cis, gis'>2
    }
  >>
}

\new PianoStaff <<
  \new Staff \rightHand
  \new Staff \leftHand
>>
