(1) Yeah, well the secure boot keys needed for Linux distributions expire in September (https://www.tomshardware.com/tech-industry/cyber-security/microsoft-signing-key-required-for-secure-boot-uefi-bootloader-expires-in-september-which-could-be-problematic-for-linux-users), so that seems like a sustainable solution, sure buddy.
(3) What’s your income? What region of the world do you live in and what hardware is available to you? I’m still using an am4 platform PC as my daily driver because I can’t burn money. One of my buddies has an AM3 PC. Many people use modified surplus office PCs (especially in developing nations like South America or SEA), which don’t have secure boot as an option. Check your privilege, and maybe donate some of your spare hardware to those who need it, if you want to make this “a non issue” for everyone.
(4) Yeah. I own my hardware, I configure my software. I gut Windows like a fish and keep it on a leash for these games, and use Linux for my work and for the games that respect the ecosystem.
On the list thing, it seems that adding numbers with periods in a list seems to auto configure it to ascending numbers. That’s why I used (1) (3) (4). Weird, but I guess that’s the work around.
Enrolling your keys doesn’t work btw, because battlefield checks which keys you enroll, only accepting the default MS keys. Also on the hardware front, it is a big problem for gamers on a sub-300 USD budget these days - the best deals are on legacy hardware or surplus office equipment, mainly AM3-AM4 era.
