Is there a way to tell grub to boot the next time (and only this time)

$ man -k reboot

Caveat: I have never used it.

NAME
grub-reboot - set the default boot entry for GRUB, for the
next boot only
SYNOPSIS
grub-reboot [OPTION] MENU_ENTRY
DESCRIPTION
Set the default boot menu entry for GRUB, for the next boot only.
-h, --help
print this message and exit
-V, --version
print the version information and exit
--boot-directory=DIR
expect GRUB images under the directory DIR/grub
instead of the /boot/grub directory
MENU_ENTRY is a number, a menu item title or a menu item
identifier.
Please note that menu items in submenus or sub-submenus
require specifying the submenu components and then the menu
item component. The titles should be separated using the
greater-than character (>) with no extra spaces.
Depending on your shell some characters including > may need
escaping. More information about this is available in the
GRUB Manual in the section about the 'default' command.
I have a bluetooth keyboard which does not work in grub. This is why
I want to tell grub, while I am on debian, to boot at the next reboot
to entry n°3 (which is a window I keep for some specific softwares).
I do not want to change grub order each time. I am looking more to
something like "touch /forcefsck" to force check filesystem (but for
booting to entry 3 in grub).
Good luck.
