Hi,
As discussed with Julian Andres Klode on IRC, there are cases where the value of grub-efi/install_devices is affected by the value of LC_COLLATE.
This is caused by this unique sort: https://git.launchpad.net/~ubuntu-
core-dev/grub/+git/ubuntu/tree/debian/grub-multi-
install?h=debian/2.06-2ubuntu7#n220
# lsb_release -rd
Description: Ubuntu 22.04 LTS
Release: 22.04
From what I see, this can only happen on systems with NVMe drives:
# find -L /dev/disk/by-id/ -samefile /dev/nvme0n1p1
/dev/disk/by-id/nvme-eui.e8238fa6bf530001001b44455555555-part1
/dev/disk/by-id/nvme-WDC_CL_SN720_SDAQNTW-512G-2000_xxxx-part1
Let's assume grub-efi/install_devices has the following value:
# debconf-show grub-efi-amd64 | grep grub-efi/install_devices:
* grub-efi/install_devices: /dev/disk/by-id/nvme-WDC_CL_SN720_SDAQNTW-512G-2000_xxxx-part1, /dev/disk/by-id/nvme-WDC_CL_SN720_SDAQNTW-512G-2000_yyyy-part1
This was obtained with this LANG/LC_COLLATE:
# echo $LANG
C.UTF-8
# dpkg-reconfigure grub-efi-amd64
- │ GRUB EFI system partitions: │
- │ │
- │ [*] /dev/nvme1n1p1 (535 MB; /boot/efi) on 512110 MB WDC CL SN720 SDAQNTW-512G-2000 │

We can see that the boxes are properly ticked here.
However:
# export LANG=en_US.UTF-8; dpkg-reconfigure grub-efi-amd64
- │ GRUB EFI system partitions: │
- │ │
- │ [ ] /dev/nvme1n1p1 (535 MB; /boot/efi) on 512110 MB WDC CL SN720 SDAQNTW-512G-2000 │

The boxes are not ticked, if I tick them, I get the following:
# debconf-show grub-efi-amd64 | grep grub-efi/install_devices:
- * grub-efi/install_devices: /dev/disk/by-id/nvme-eui.e8238fa6bf530001001b44455555555-part1, /dev/disk/by-id/nvme-eui.e8238fa6bf530001001b44666666-part1

- I assume the postinst script for grub-pc exhibits the same bug.
