-dgui option dropped in 2.24 - how to stop the black box on Windows now?

[Richard Shann]

There was an option -dgui which allowed Denemo to run LilyPond in the
background on Windows, but this has vanished without, as far as I can
see, any entry in the Changes to account for it

https://lilypond.org/doc/v2.24/Documentation/changes-big-page

Is it possible for LilyPond 2.24 to be run in the background? 
As it is an ugly console pops up blotting out the user's view of his
work and preventing him continuing to enter text/music until it is
done.
