If you are using a typical distro like fedora, debian or ubuntu, and you are wiping everything, you don’t really need to know anything. The installer will handle everything for you. Just delete all partitions while installing and start fresh and it should all just work.
If your install media refuses to boot for whatever reason, then you may have to disable secure boot in the system EFI/BIOS menu.
Most users likely do not know about recall, and as the guy in the video shows, there doesn’t appear to be anything in a normal user interface showing that it is installed and configurable.
