Need Help/Bios Mod Z370 AORUS Gaming 7

Hi! First of all english is not my mother language, sometimes using translate apps, sorry for any mistypo.

I have Z370 AORUS Gaming 7 motherboard. Need to enable SPD Write but there is no option visible in bios.

When ı try to open bios with AMIBCP5 it says:

Maximum number of strings per section exceeded. Setup Configuration and BIOS String tabs will not be shown.

When ı try it with AMIBCP4 it opens but lots of setup configurations says undefined and ı dont know what they are.

When ı search spd word in bios strings SPD Write Disable string is there but ı dont know hot to edit it.

I try to use uefıtool. Shows security protect. AMI v2 protected ranges hash file found at base 00FC18F0h.
Only view options enable, ı can not change anything.

Here is my bios file: Z370AOG7.F15 - Google Drive

Here is modded bios with flash files.
