@Woglyte - AMIBCP program (5.02.0031) would be used to make those test BIOS.
The changes would be made at IntelRCSetup >> IIO >> IIO 0-3 (IOU0-2), and what you see there does not directly correlate to which PCIE slot it is, that’s why I mentioned it may take many BIOS to find which one affects which slot
And, each BIOS you make/edit needs to be on extract body from capsule, then once done, inserted back into stock capsule. This is done with UEFITool, right click AMI Capsule and extract body, then this is what you edit.
Once done, open stockBIOS.cap in hex editor, go to 800h, open mod BIOS in second tab of hex editor, select all and copy, then at stockBIOS.cap at 800h you paste your mod BIOS and save as USBFlashbackName.cap (X99A.CAP)
Here is 12 11** (due to below) BIOS with each possible setting set to 4x4x only for now, once you ID which slot is affected by which BIOS, let me know and I will make you new final BIOS with only those settings applied to those two slots you wanted.
Also, depending on how many NVME you have, you need to stick them in certain slots on the Hyper card, but I’m not sure which slots for xx number NVME
** Actually, one slot is already set to 4x4x in stock BIOS, or at least one of the possible setting place options (*IIO 0 >>IOU2 (IIO PCIe Port 1 - but keep in mind this may not be PCIE Port 1) , it’s already 4x4x when optimal defaults is loaded.
So, try all slots right now with stock BIOS, one slot may be 4x4x capable. Additionally, only this one setting type/label per IIO has 4x4x, rest only have the following >> 8x8x, 8x4x4x, 4x4x8x, 4x4x4x4x

Here’s outline of BIOS test package, two of these BIOS will be set to and possibly have some slot set to 4x4x (like the stock BIOS, is third of three possible BIOS that can have 4x4x option set), rest will be set to 4x4x4x4x for this test.
All BIOS will have same USB Flashback name here, so be careful not to mix them up, and please take notes, tell me whatever you observe per BIOS, per slot, so I can keep in folder for this BIOS in case anyone needs edit later.
Each BIOS should be tested with card with single or dual NVME at least, and this adapter should be tested on each slot. All slots should be tested with each BIOS, including a re-test by you of stock BIOS since it has 4x4x set by default for some slot possibly
IO 0 >>IOU2 (IIO PCIe Port 1) = 4x4 = stock BIOS setting - Will leave this set in all BIOS below
IO 0 >>IOU0 (IIO PCIe Port 2) = BIOS #1 = 4x4x4x4x
IO 0 >>IOU1 (IIO PCIe Port 3) = BIOS #2 = 4x4x4x4x
IO 1 >>IOU2 (IIO PCIe Port 1) = BIOS #3 = 4x4x
IO 1 >>IOU0 (IIO PCIe Port 2) = BIOS #4 = 4x4x4x4x
IO 1 >>IOU1 (IIO PCIe Port 3) = BIOS #5 = 4x4x4x4x
IO 2 >>IOU2 (IIO PCIe Port 1) = BIOS #6 = 4x4x
IO 2 >>IOU0 (IIO PCIe Port 2) = BIOS #7 = 4x4x4x4x
IO 2 >>IOU1 (IIO PCIe Port 3) = BIOS #8 = 4x4x4x4x
IO 3 >>IOU2 (IIO PCIe Port 1) = BIOS #9 = 4x4x
IO 3 >>IOU0 (IIO PCIe Port 2) = BIOS #10 = 4x4x4x4x
IO 3 >>IOU1 (IIO PCIe Port 3) = BIOS #11 = 4x4x4x4x
