Uefi firmware won't load

I think the issue is you have Intel Raid disk.

Hardware-1: Intel 82801 Mobile SATA Controller [RAID mode] driver: ahci v: 3.0 bus-ID: 00:17.0 chip-ID: 8086.282a 
Drives:    Local Storage: total: 232.89 GiB used: 8.28 GiB (3.6%) 

When you installed EndeavourOS were you able to boot into it? Is there a setting in your Bios for Intel RST?
