[Request] Gigabyte GA X99P-SLI Bifurcation support for x4 Hyper m.2 card usage

Looking for a modified BIOS for a Gigabyte X99P-SLI motherboard.
Want to add a x4x4x4x4 m.2 card to a x16 slot for a project.
Got a modded BIOS for my Asus server/workstation board last summer…but this Giga board has been more difficult.

Thank you in advance.
