[Request]Aspire 4738Z BIOS Unlock

This is my first time posting in this forum, I got no idea what to do to unlock those hidden settings of my BIOS, I have tried to look for solutions but there is none, I hope this forum could help me.

I used the phoenix tool to extract some data from my BIOS but I got no idea what to do after that, I appreciate if someone would explain the way of doing it to me.

Please help me to unlock the hidden settings for my BIOS, thanks in advance.
