You mean, 4 quavers/eighth-notes.

You could try something like
\version "2.24.3"
\language "english"
\new Staff \relative {
\time 2/4
\set Timing.beamExceptions = \beamExceptions { 8[ 8 8 8] |
16[ 16 16 16] 16[ 16 16 16] }
c''8 16 16 16 16 8
8 8 16 16 8
8 8 8 16 16
16 16 8 8 8
8 8 8 8
}
Extra lines may be needed to cater for tuplets if you have any.
