It’s the installation screen that allows to secure the boot, by default swithing it enabled. However, due to the lack of competence (SUSE developers, have in mind), it’s never launched. Instead, fatigue triggerred errors are implicit, like launching side kicked media boot, e. g. Gentoo administration CD.
Nevertheless, besides that, BIOS UEFI settings set on secure boot (already, not allowing to launch other media ISOs), it’s not reactive. Setup mode is still on, not changing into user mode whatsoever, implying the developer care should solve these problems, which is basically social security and fire off (open) SUSE developer team.
