I don't have the ability to update the BMC firmware. It should be under maintenance according to the manual. But it's not present.

This is a Datto server that has a (modified?) ASRock Rack D2143D8UM motherboard.
I would like to put the original ASRock firmware on it because I don't have Fan Control through the IPMI interface and I'm hoping flashing the original ASRock firmware might fix this. I also have a bug where the DDR4 temperature sensors go in the red reporting 255℃ when I ran PassMark MemTest86
Is this even possible? If so, is it safe to update the BIOS and/or BMC firmware because it's a Datto branded server?
This is the information I see on my Dashboard
