[REQUEST] (AMI) DFI Mini-ITX HD100-H81

[metaspace]

Hi i have a Dfi-Hd100-H81 motherboard. It is a LGA 1150 mini itx motherboard there is not much info to be found on the web. The problem is that the bios has no CPU voltage settings, and I would really like to under volt it to save on power. Are there any BIOS mod or a way to unlock the voltage settings maybe a hidden menu? I will be using it as a pfSense firewall, so the lower, the better.
a fully unlocked bios is it possible, I hope it is. Thanks!
