Disable Secure Boot to install Silverblue?

Hmmm. Hadn’t thought of that. Might give it a try.

Remember that RHEL and CentOS are both server oriented and do not have the gui support one gets with all the various spins of Fedora except the server edition.

Both come with Gnome on desktop variant … for many user case scenarios all you really need is i3, log in, startx …
