GA-Z77X-UD5H Gigabyte +2TB exFat Disks stuck splash screen

Hi, can please someone help me to unlock all the features of this bios?
And most of all I need to fix a strange problem, that happen on another gigabyte mb, and was fixed via bios but I’m not able to do it: bios is stuck at splash screen if an exfat disk is inserted +2tb, and i have two 4tb disks that i want to make it work, if you please can fix this like this guy did modding bios, Disks work if hotplug in windows but can’t boot or pass bios splashscreen or go in bios if it is attatched [SOLVED] Gigabyte GA-Z97X-UD3H cannot boot in AHCI mode if HDD initialized in GPT - BIOS/UEFI Modding / BIOS Modding Guides and Problems - Win-Raid Forum (level1techs.com)
