This is controlled by the stroke-style property of the Flag:

\version "2.23.3"

\language english

slash = \tweak Flag.stroke-style grace \etc

\relative c
{
  \clef bass
  <<
    {
      <b' fs>2 \afterGrace <as e>2 \slash <as e>8( |
      <fs d>1)
    }
    \\
    {
      <d b>2 \afterGrace <cs fs,> \slash <cs fs,>8( |
      <b d,>4)( <as cs,>4 <fs b,>2)
    }
  >>
}

I removed the 3/4, as this is the standard anyway as long as you don't 
modify afterGraceFraction.
