Hello Hitman . Thank you very much for your answer.
I think there is no point in rebuilding since I can boot the system manually, that is, Grub Libreboot works. But I can’t figure out how I can change grub.cfg and then flash it into flash memory so that it doesn’t give errors and boots the system correctly.
As for where it was taken from, I’m attaching information here for those who are looking for answers:
Libreboot’s argon2 patches are based on this AUR repository https://aur.archlinux.org/cgit/aur.git/tree/?h=grub-improved-luks2-git&id=1c7932d90f1f62d0fd5485c5eb8ad79fa4c2f50d which patched GRUB 2.06, and the patches were rebased for use with GRUB 2.12 which Libreboot uses; the rebase was performed by Nicholas Johnson. Nicholas emailed me to tell me that this had been done, and I then merged Nicholas’s work into Libreboot. Thank you, Nicholas! Thanks also go to Axel who is the author of the original work that Nicholas imported from Archlinux AUR.

Without installing Grub from the repository I see messages:
"Booting from Hard Disk..." and nothing happens.
If I install grub from the repository I see the error:
error : disk 'lvmid /WuGDE4-Po2w-3n6d-9pcY-sqsoV-eTsq-aLxagJ' not found
I am attaching grub.cfg Libreboot (below). I made the changes then flashed it, but it didn't work.
