Enabling Hidden Grub Menu in Silverblue 29

I would like to test the F29 hidden grub menu feature, on my laptop it is not enabled by default because i rebased from SB 28.
Do we have a procedure to enable the feature on Silverblue? Is it safe to modify the grub environment (by running grub2-editenv) on Silverblue or this can lead to problems?

So i have tested by myself that it works :slight_smile: , to enable the feature just do

grub2-editenv - set menu_auto_hide=1


Never heard of this before, what does it do? Just doesn’t show the GRUB menu or something?

Edit: found it. This is cool, thanks!
