I had it in /etc/init.d/local.start back when I used these features.
Nowadays with openrc I would put this line
in /etc/local.d/grub-default.start. I had some safety checks included,
like testing if networking and sshd was running, so this box would be
accessible from remote. But this is some years ago now, currently I do
not administrate such remote servers and so I have not used this
mechanism for a while.

The first line in /boot/grub/default has the number of the default entry.
grub-set-default modifies this file, as does the GRUB savedefault command.
