Unlocking chipset tab in bios on ROG Crosshair VIII Impact

[SuziF]

Hi all. I recently purchased an Asus ROG Crosshair VIII Impact motherboard. For some experimentation, I would like to unlock the "chipset" tab in the BIOS.
In the AMIBCP program, I unlocked all the hidden settings, but after flashing the modified BIOS, the "chipset" tab did not appear in the settings menu.
Please tell me how can I unlock this tab myself? I will be very grateful to you.
