How to delete or hide the lower staff on a piano score?

I searched the forum and found out that it seems to be possible to hide the lower piano staff, but I have no idea how to do this …

Check out Layout options -> Vertical spacing -> Hide empty staves
I often have a hard time finding it myself, even though I use it a lot

YES!

Thanks a lot.

Or right-click > staff > remove staff

That option didn’t exist two years ago.
