The issue you are running into is that overrides won't work on a single
item when there's more than one of them happening at the same moment in
the music. As these are (basically) notes within a chord, they're at the
same moment. And the \hide command is just a shortcut for an override on
the grob's Transparent property. In the case of simultaneous grobs, you
want the \tweak command.
http://lilypond.org/doc/v2.25/Documentation/notation/tweak-and-single

So, your code would become:

\version "2.24.2"

up = \drummode {
  \slurDown \grace { sn16 sn( }  <cymc \tweak transparent ##t sn) bd>4
}

\score {
  \new DrumStaff <<
    \new DrumVoice {
      \voiceOne \up
    }
  >>
  \layout {}
}
