Disable Grub2-Bootmenu

Hello together,

how can I completly disable the grub2 boot menu?

In Yast2 I have the option to hide the boot menu.
However I can open the menu by pressing the “ESC”-Button.

Is it possible to disable these interaction method?

Hi
AFAIK, no easy way, best to add a password for grub via YaST Bootloader if users have physical access. Did you set the timeout to zero as well?

I set the timeout to -1. That is the lowest value.
If I press “ESC” at the right time, I can access the bootmenu.

Timeout 0 and passwort for bootloader changes seems to be the correct settings.
Otherwiese I can enter the boot-menu
