Gigabyte B760M DS3H AX Bios setting?

[Vogon]

Hi I recently built a system with this motherboard, when stress testing with intelburntest I noticed the power draw from the cpu is in excess of the 65w rated for the i5 12400f.
I assumed ths may be due to a bios boost feature. The only thing I can see that looks a likely suspect is a Gigabyte performance mode.
But all but the one option it is on is greyed out, so IDK how I can disable this feature and have it run the intel stock settings. If you have any ideas how this can be achieved please let me know

But it does appear there is a bios boost of some sort in place, TBH all I want to be able to do is set it to default !

Hi Tetras, thanks for taking the time to give a detailed reply.

Pics of the bios:

The Turbo power limits I changed to Intel POR and seems like it now pulls back the clocks when it exceeds 65w, as expected.
But I can't change the GB PerfDrive in either easy or advanced mode, Optimization is the only option, I can not see a disable !
