BIOS autorestore on GIGABYTE dual-BIOS motheboard?

So I flashed a Non-K BIOS on my GIGABYTE GA-Z170-HD3P paired with i5-6600, played with it for few days, got a solid OC to 4,4G on CPU and 3G on RAM and after I switched my RAM modules for different ones to OC them, for hours I couldn't get an OC by a single MHz by BCLK. After them wasted hours, I noticed the problem - the BIOS was back on version 5, instead of 5g, which is the Non-K one.

I noticed the MB has 2 BIOS chips, one propably for a backup one, so it must have restored (or switched) the original one without me even knowing or noticing. Have you got any idea how to switch them or to prevent this in the future? The manual says nothing.

    Unless there is a switch on the motherboard to switch between the 2 chips (which there used to be) there is no guaranteed way to force it, its completely automatic, the backup bios only kicks in if it detects a problem with the main bios, there are guides and things you can try to force the backup bios, if thats the one you want to use, but non of them worked for me on the newer boards: https://www.gigabytenordic.com/gigabyte-tips-tricks-rma/
