Kalpa and/or Leap 16.1 immutable: can I change the GRUB sceeen delay?

English Install/Boot/Login

Maybe it’s a silly question for most, but after years of being spoiled with YAST, is it possible to change (shorten) the time delay on the GRUB screen at boot? Immutable versions are great, but I wish I could change some things more easily. What file should I edit to do this? Thanks.

Check for timeout in this file:

:~> cat /etc/default/grub  <==== this file

# If you change this file, run 'grub2-mkconfig -o /boot/grub2/grub.cfg' afterwards to update
# /boot/grub2/grub.cfg.

[ ... ]
GRUB_HIDDEN_TIMEOUT_QUIET=true

GRUB_TIMEOUT=8      <======== timeout value 

GRUB_CMDLINE_LINUX_DEFAULT=
[ ... ]

Run update-bootloader --config after changing or use cockpit-bootloader…

Immutable transactional-update grub.cfg on Leap only…

yes, modify /etc/default/grub like @myswtest indicated, and then run transactional-update grub.cfg as @malcolmlewis suggested.
