I think OEM bussiness machine was not designed for overclock , so it should not contain OC feature.
It only can unlock an hidden AMI menu.
I have some question to ask you.
The bios update package from HP website that the bios size was 1677216byte ,but your backup bios size was 2097152byte ,why??

How do you think to reflash your backup bios again ??
According to my experience on HP Pro 3300 sff that bios was lock ,i only can backup bios by "Intel fpt " ,other tools were disable.
Mod bios can't reflash by any flash utility.
So i desoldering bios chip and read it from SPI hardware programer , and open it from Intel "Flash Image Tool" to edit Master Access Section.
CPU/BIOS and Manageability Engine (ME) ,edit Read and Write access value to 0xff.
After this modified , and resolder chip to motherboard ,now i can freely to dump complete bios (MEI area) or write bios(MEI area) by Intel fpt or afuwin or afudos either.
Here is my menu unlock on HP 3300 sff.
