Lenovo M700 BIOS

Hi everyone, I’m trying to add a cpu microcode to allow my Lenovo M700 to have KabyLake processors, but I’m stuck becouse I can’t add the new microcode.
I have the bios.exe (m05jy83usa) and themicrocode I want to add ( cpu906E9_plat2A_ver000000B4_2019-04-01_PRD_DACDA920) or replace to cpu506E1_plat22_ver8401001A_2015-03-10_PRE_56A790FF.
Can you help me?
If I extract the bios.exe I have a bios.bin and I’cant open it with MMTool, so I can’t add the new microcode
Thank you so much
