Motherboard does GA-Z77N-WIFI motherboard support bifurcation?

[oldnick]

I want to install raid card and 10gb nic into this board (GA-Z77N-WIFI)

is it possible via bifurcation ?

Alas, I'm coming up empty in my searches. Usually boards that support bifurc have a setting in BIOS to configure lane splitting - I can't see one in the manual for that board
