Dell Vostro 360 All In One bios mod

Hello!
I've just bought an Dell Vostro 360 BTS All In One Desktop Computer.
Current bios is A06 from Dell:

This AIO Computer has an Geforce GT 525M inbuild.
I have seen many people using a vbios mod to update the 525M to an 540M or 550M by undervolting.
I have been told that it's not possible on my bios, because the vbios is protected by EFI.
Any chance to unlock or modify this?
Thanks a lot!

You can make the card a 540M or 550M by overclocking, I don't see why you would want to undervolt (that could actually hurt your overclock).
But why even do that with a bios mod?
Why not just use nvidia system tools to overclock?

Thanks for you answer!
Because by undervolting but rising the clock of the card, it would not generate much more heat.
Because with the bios mod I could make it permanent.

My nvidia GT525M is not supported by nvidia system tools
