UNlock ASpire GX-781

[REPEINAO]

Hi there, I'm REPEINAO, and this is my last resort hahaha.
I have an Acer Aspire GX-781 motherboard and I'm trying to overclock an i5 6500, but the BIOS is completely locked down with no overclocking options at all.
I've tried every possible way to unlock or enable the BIOS settings, but I'm not an expert at this, and ChatGPT hasn’t been much help to be honest.
I just can’t figure out how to get it to work or show the overclocking options.
