This doesn't exist in the MIDI norm, but you can do

\set Staff.midiMaximumVolume = 0

Please refer to
https://lilypond.org/doc/v2.22/Documentation/notation/controlling-midi-dynamics.fr.html#setting-midi-volume

If you want a staff to be silent not on a
particular passage but on the whole score,
you can also \remove the Staff_performer.
This differs from setting midiMaximumVolume
in that it will not output the notes with
volume 0, but stop outputting the notes at all.

\version "2.22.1"

\score {
  <<
    \new Staff \with {
      \remove Staff_performer
    } {
      c'
      d'
    }
    \new Staff { e' f' }
  >>
  \midi { }
  \layout { }
}

Best,
Jean
