Bios Mods -The Best BIOS Update and Modification Source

I don't even know if this is possible but I have a P55A-UD3 that I am using for a VSphere 5 whitebox and everything works awesome until it comes to certain servers that needs IOMMU. I was wondering if unlocking this feature was possible. Here is the BIOS.

5 year old bump. Emailed Gigabyte support, but I don't expect an answer from them. On the GA-P55A-USB3, it was enabled with the "advanced" options that require Ctrl+1 to be entered in the BIOS. I imaging it's built into Gigabyte's rom already, just not enabled. The chipset and my CPU support it, just not the BIOS. Any help would be greatly appreciated.
