Are you able to update this with a Bios update on your hardware? We are lacking sufficient information here. What is your hardware? Do you have Eos installed? Do you have Windows installed? Please psot a link for your hardware.

If you have an EFI executable then you can do this via an EFI shell - this isn’t an EndeavourOS-specific thing, so your hardware manufacturer will have documentation.
If you don’t have a way of accessing a shell via the EFI then have a read here: https://wiki.archlinux.org/title/GRUB#UEFI_Shell
Most firmware updates on newer hardware can be done automatically within the UEFI screen. Or a lot also are automatically done with updates from Windows and on reboot it automatically performs the upgrade. I have done this many times already on my HP laptop and my Lenovo. On my desktops i do it from the UEFI setup screen via a usb drive or directly from via network.
I have never used any of the Linux tools to update firmware. Someday I’ll have to try that fwupd tool.
God forbid backdoor would be outdated…
