The UUID in the BIOS is NOT VFAT volume. It is something completely

It should be the UUID of the partition, not of the VFAT volume. The
partition UUID is stored in the GPT. The volume UUID is stored in the
filesystem header (I believe).
For example, on my laptop:
# efibootmgr -v | grep Fedora
Boot0000* Fedora
PciRoot(0x0)/Pci(0x17,0x0)/Sata(2,65535,0)/HD(1,GPT,39484dd8-b1d9-47b2-b4d7-89dfe3ce5e09,0x800,0x12c000)/File(\EFI\fedora\shimx64.efi)
# blkid | grep sda1
/dev/sda1: LABEL="ESP" UUID="3850-574E" TYPE="vfat" PARTLABEL="EFI
