when I edit /etc/default/grub to reduce the GRUB time while booting fedora from 5 to 2 seconds, I save the file, but upon restart, the grub time is agian set to 5 seconds.

Is there some kind of update grub I should do?

[ -d /sys/firmware/efi/efivars ] && echo EFI || echo Legacy Bios

=> EFI

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Actually, it doesn't. It's been updated, I even installed Grub Customizer, and the Grub timeout is 2 seconds, but it still couts down from 5 when i boot it?

You probably have an EFI system, see the other answer...
