How about using; \once \override NoteColumn.force-hshift = #1.0
Here is the code:
\version "2.24.1"
global = {
\key c \major
\time 6/8
}
rightOne = \relative c'' {
\global
% Music follows here.
e16 f f dis dis! e
}
rightTwo = \relative c'' {
\global
% Music follows here.
d16 g, g \once \override NoteColumn.force-hshift = #1.0 d'! \once \override
NoteColumn.force-hshift = #1.0 d! g,
}
\score {
<<
\new Staff = "right" \with {
midiInstrument = "acoustic grand"
} << \rightOne \\ \rightTwo >>
>>
}
