Insyde v2.15 BIOS Unlock

Hello all,

I have been looking around and have yet to come across a BIOS unlock specific to my circumstances. My laptop is an Acer Aspire E1-531 and the BIOS is Insyde v2.15. I am hoping to unlock the advanced tab so I can see what can be tinkered with. Any help on the matter will be massively appreciated.

Thank you for reading!
