Acer Aspire F5-573G extend overclocking limit by editing bios option

Hello , I have an Acer Aspire F5-573G laptop , want to extend overclocking limit by modding bios , but bios is rewrite-protected.
But i saw a thread before , if can’t make advance setting visible by modding bios , it’s possible to change bios settings by direct edit of bios options and NVRAM.
So is it possible to extend overclocking limit with that way ?
