AFAIK this patch[1] allows to have several passphrase attempts. It was
originally proposed by John Lane as a part of crypto enhancement patch
set[2].
Several versions of this patch set were sent to grub-devel mailing list
in 2015-2018, but nothing was directly included into git. The patch was
written
for LUKS1 version because support for LUKS2 in grub was included later.
However, it seems it would be trivial to add support for LUKS2.
I've actually completely solved this through scripting thanks to what
I've learned from Maximilian Stendler's Github repo (who replied
earlier).
There's a weird trick to it though, where you make a tar file with a
simple cfg in it that sources another config and then you have things
like functions, loops and if tests available.
Working great now, thanks to him.
Cheers.
