How to open adjustable voltage range?

Hey,

i hope someone can help me to modify my bios. I’m wondering wich setting and file i have to edit to mod the adjustable voltage range.

For the board Asus Strix B450-I Bios 1201 i was able to set the CLDO VDDP Voltage from 0mV to XXmV in 1mV steps. In the new 2703 Bios i’m only able to set the voltage from 700mV to XXmV.
What file and setting do i have to change that i’m able again to set it down to 0mV?

Thankful for any help

sometimes it depends on your hardware in which steps you can choose voltage. setup module is where you can edit the voltage range.

Same hardware just different Bios. The part in the setup module looks like this but i’m not sure if this is the right part to change the range?
