To dual boot with NixOS and other operating systems it would be nice to have 'chainloader' so that this configuration would work:
(bootloader
(bootloader-configuration
(bootloader grub-efi-bootloader)
(target "/boot/efi")
(menu-entries
(menu-entry
(label "systemd-boot")
(chainloader "/EFI/Boot/bootx64.efi")))

I just got a librem13v4 with PureOS installed booting via Coreboot amd grub,
and found that it will boot legacy mbr usbs, but would not boot a UEFI-bootable
USB or system on external USB SSD, though it shows up in a list of bootables.
(I've seen a reference to some kind of tool that converts a GPT partition to MBR style,
but I don't want to do that).
Does anyone know if efibootmgr and coreboot see bios nvram compatibly?
Or a workaround?
I saw your post and am hoping to find a possibly similar 'chainloader'
solution, but worry that the second loader may mess incompatibly with bios nvram.
