There are probably distros out there that don’t need secure boot.
My computer does not have secure boot and Installed Kubuntu 26.04 without issues. I was running Ubuntu 22.04 for a long time prior, and had no install issues.
I'm not trying to sound harsh, but this whole issue evolves around the software and hardware companies having control over our systems, and not the other way around. I simply refuse to give them that ability, to the best of my ability.
