ill upload the hyve bios if someone has the knowledge to mod just to add the fan setting.
the BIOS has no control over the FAN controller, which are under BMC administration.
but in systems with BMC, the BIOS can send FAN control options to the BMC.

I have limited knowledge but i will try to activate fan options, i can see they exist in amibcp, is it possible to modify bmc file just like bios file?

no, there is a linux/minix running. but you could inject a SDR to tell the BMC custom FANs are there.
AMI BIOS comes with all options, even the ones that doesn't apply, the author has to hide remove them.

would it be possible to run the server with bmc completely disabled? i saw somewhere people were getting error 78 on their server with bmc on and no error when disabled. trying all possible scenarios right now

Unfortunately no, any tyan bmc hangs, the bmc on this thing is a openbmc version above 2.0 you can try to build one if there is newer but thats out of my league
