https://forums.opensuse.org/t/how-to-have-a-custom-uefi-grub-menu-for-a-multiboot-system/133541 could help you get that started. /etc/grub.d/40_custom and 41_custom are designed for custom stanza creations. If you wish their result to head the selections in you Grub menu, you must rename whichever you choose to use so that it sorts before 10_linux. I use both avenues, so copy 40_custom to 06_custom, and 41_custom to 07_custom. Updates will at some point restore the original 40_custom and 41_custom, unless you keep and either empty them or make them nothing but comments.
This was just for a live image. There's no need to get that crazy complicated. That's only for a multi-boot system. Adding items to a single boot system is very simple.
Adding a stanza to 40_custom is not complicated. That URL is mainly example of configuring grub, getting to know how it does what it does, good for people who learn better from reading and/or working with examples than reading man pages.
Fedora uses BLS now, so that information is somewhat outdated. It probably still sort of works, but not the best way.
