GA-P67A-D3-B3 rev.1 and upgrade to UEFI

Hello, i found my old parts and i have a GA-P67A-D3-B3 rev.1 motherboard.
I would like to update Award BIOS to UEFI.

I see Gigabyte share on official website a UEFI beta version of BIOS, but for rev 1.1 GA-P67A-UD3-B3 and GA-P67A-D3-B3 (rev. 2.0)

It’s possible to update rev.1 to rev.1.1/2.0 and flash a UEFI version of BIOS?

Can someone help me?
