Hi. I need to add support for 6-10+ SATA3-disks. Currently I have 1 free M.2(NVME/NGFF) port and no free SATA ports. So I wand to add SAS/U.2 ports and split them on multiple SATA ports. I have found [URL=https://aliexpress.com/item/32964367145.html]this[/URL] thing, but it requires a PCIe slot bifurcation. Looks like stock BIOS on my motherboard doesnt support this, but I wonder if there is any workaround.

So my questions are:
1. Is there a way to make this card work on my motherboard?
2. If yes, then will those disks be available in IRST to be used in RAID? //Assume that SATA-disks will be connected directly to this card using splitter like [URL=https://aliexpress.com/item/32999040744.html]this[/URL] one.
3. If no, is there any other way to add more SATA-ports with no/low speed loss?
4. Any advices on 5.25 HDD Bay choosing?

System config:
