No. Not if you're realistic, you don't.

Firmware RAID only exists because of Microsoft's licensing policies.

Windows can create and manage RAID sets of various types just fine. It
can do RAID 0, 1, 0+1, 10, 5, 6 etc.

But this is considered server functionality and so only the server
editions of Windows are permitted to do it. Workstation editions will
only do striping, with concomitant loss of reliability. Presumably the
logic extends to "so you need to buy a server to keep your stuff on
safely."

So, because the actual software RAID functionality in Windows is
disabled in workstation editions. PC vendors have re-implemented it in
the cheapest possible way, in the firmware.

DO NOT USE FIRMWARE RAID IN LINUX. AT ALL, EVER, UNDER ANY CIRCUMSTANCES.

If you need a software RAID, use Linux software RAID.
