Unlock Voltages on Mibook Air 13.3 (TM1604)

[Fusseldieb]

Hi there,
I've searched all over the forum and couldn't really find anything useful.

I have an Mibook Air 13.3 which has an Insyde UEFI BIOS, however inside Windows using ThrottleStop all Voltage sliders are locked. I want to undervolt it.

I am aware that this notebook MIGHT have write protection, but I do have a SOIC8 and a BIOS programmer.

How can I dump the BIOS in the first place (prefferably without disassembling the notebook)?

Thanks in advance!
