@allnet7 - I see on BIOS-mods forum you need graphics option ungrayed, this is not an optional setting (only text to show you amount) This BIOS does not have a setting for IGD/dGPU, Int graphics etc memory option, here is all the graphics related options
Also, unless you have a hardware flash programmer (Like CH341A) and SOIC8 test clip cable in your hands and have made a backup that you've verfified is proper BIOS, do not adjust any display related settings or you may end up with black screen and now way to blind flash to recover

Many Thanks for the quick help.
You are right. Sir. It´s an APU based system that´s why I got some reserves about the Gpu but wasn´t sure.

I´m new at Bios modding but not a noob and I can take some chances.
I want to learn anyway and if you can provide me with some good links, I´ll appreciate. with intel based system, all the tutorials are somehow easy to follow. with a system like mine not all the tools are working.
Although if you can pm me with the tools you used, I will compare my original with your results to study in depth on how you came to my bios unlock to help others in the forum and relieves some of you that may be busy with more advanced features for our users.
On that note, would you mind to attend my request? if you are no taken with other matters.

Gratefully yours and hopes to ear you soon.

@allnet7 - You're welcome! I agree, sometimes Intel is easier to play around with. For future reference in case anyone asks, how do you flash mod BIOS on this system?

I only used IDA assembler, UEFITool, and hex editor for this edit (only changed two bytes in hex = total mod)

This difference file has been created by IDA - Section_PE32_image_DriverSampleDxe_SetupUtility_body.efi
0000000000001306: BD >> Change to >> 00
0000000000001325: 9E >> Change to >> 00

I do not know a guide to show you how to do this exactly, this one may get you similar result, but I didn't run through this and see if it applies to your BIOS or not, you can check and see if you get same result as above changes I made
