Still working on enabling Secure Boot on Gigabyte BIOS. So far all methods offered on several forums and sites require expertise I lack. I am stuck as the BIOS need to be on User Mode to enable Secure Boot. Manufacturer Gigabyte Technology Co. Ltd. Model B360M HD3 (U3E1) W11 installed flawlessly without Secure Boot on. Do I assume correctly that as my system support Secure boot I don't have to enable it and I wont have any issue with updates and future upgrade.
