BIOS Unlock Request for Acer Aspire 5742

Hello everyone and good morning. This is literally my first post on a BIOS modification forum so I'm basically a layman at the moment.  

Let's get to the point, I have an Acer Aspire 5742 notebook (No G or Z ending, just Aspire 5742). Well, I've always been curious and would like to know if there is any way to unlock the BIOS advanced options tab for this notebook and any other that is hidden.

I know it's an old notebook, I've been doing research here on the forum and found a lot of information about BIOS Mod for Acer Aspire 5742G and Z, which have Nvidia VGA. But for 5742 only (Model without NVidia VGA, only video integrated into the CPU) found some vague reviews and no real dedicated BIOS Mod for it. (I also have no idea if they are compatible with 5742 without G)

Most of the conversations about this model date back to 2011/2012 so I don't know if anyone is still able to help me in 2025. So if anyone can provide me with a BIOS Mod to unlock the advanced tab and any other hidden ones I would be very grateful. 

I don't have a defined goal in unlocking this BIOS, it's just curiosity and madness on a holiday morning. 

Information:
Board BIOS version: V1.04
Model: Acer Aspire 5742
Motherboard: PEW71 with HDMI

I know there are more updated bios available like 1.28, 1.29, 1.30 but they are unavailable on the Acer website 404 not found.
