Can't space staves in gallery mode

I haven’t been able to find how to move staves around in gallery mode. There is a setting that applies to all, but that’s all I can find (and some very old posts). I just want to widen the gap in one place and not have everything else affected (e.g. when there are a bunch of lyric lines - they collide with the next staff). Please advise.

In galley view there is only one global setting (under Layout options>vertical spacing). You could perhaps change it, then change it back?
