Plymouth: disable status messages

I installed Plymouth on a LUKS encrypted machine. Works fine. Theme is Spinner, in case it matters. I'd like to modify one thing, though: After entering the LUKS passphrase, there's a status message cryptsetup: nvme0n1p3_crypt set up successfully showing for 2-3 seconds. Is it possible to get rid of it? In /usr/share/plymouth/themes/spinner/spinner.plymouth there is a MessageBelowAnimation=true option, but that's just for the position on the screen. Is it possible to completely hide the status messages?
