I want to install H410M H V3's OpRom file to X470 K4 BIOS.

Hello, I bought a unusual SSD(Virident FlashMax II) and on my ASSRock X470 K4 motherboard doesn' t boot even I turned on CSM and OpRom options to Legacy only. But I tried this SSD on the Gigabyte H410M H V3 motherboard it works great when I turn on CSM Support, Storage Boot Option Control to Legacy, and PCI Devices to Legacy. 
So I want to install H410 H V3 BIOS' OpRom code to my X470 K4 BIOS.
Does anyone can do this one? Please, I really want to use this SSD because I don't have much storage capacity without this SSD.
X470 K4's BIOS file is in the attachment, and H410 H V3 BIOS is here; https://download.gigabyte.com/FileList/B...d2b14e13cf 
Thanks in advance!
