[REQUEST] dell xj8c4 skylake non-k Overclock and coffelake support

Hi, i’ve boguht a z170 dell xj8c4 from a friend, from a dell xps 8900.
It is possible to make it overclock non-k skylake? ( i use a asus z170 with a g4400 overclocked at @4.5ghz, but the board have some problems with audio and ram )
Also it is possible to make non-k skylake + 8/9 gen support bios?
Thank you very much guys
Have a good week.
