acer aspire 5920g bios request

I've been banging my head against the wall searching for an unlocked bios for my aspire 5920g.
My problem is that it doesn't have the advanced tab unlocked.

I respectfully request an unlocked bios with this feature - active advanced tab.
Link to manufacturer bios: http://support.acer-euro.com/drivers/not..._5920.html -> version v 1.3813

Thank you in advance and a good day!
