You should ask the mainboard manufacturer Intel for a BIOS with updated Intel Management Engine Firmware. A firmware of the v8 series should be available for your X79 mainboard.
Edit:
If you should not succeed this way, you may look into this thread: http://www.overclock.net/t/1360980/gigabyte-ga-x79-up4-no-new-x79-chipset-and-management-engine-interface-drivers
By the way: The latest Intel Management Engine Interface driver, which may work with your system, seems to be within the Intel ME package v9.0.2.1345. You may try it.
