Asus z270-p change default settings

[Asusz270problem]

Hi,

I have a problem, my PC suddenly get down with CMOS, and if that happen i need manualy start it and change bios settings (was option APM - power on).
Can someone make bios version with another default settings and disable warning (such a new processor installed press F1..)

4g - enabled
APM - power on
peg1 - gen2
peg2 - gen2
disable warning on start

thank you.

PS If that possible maybe you give me some link with tutorial how i can do it by myself
