BIOS file problems

Good day all,

I have modded my MSI Z270 Krait bios but it appears as a .bin file after modding. My msi motherboard does not recognize the .bin file but would recognize the .A90 file instead. How do i convert the .bin to .A90 or can the AutoModTool create an A90 file? Need help ASAP, thanks
