I’ve tried to modify it myself using AMIBCP.
And I’ve try to flash it via AFUWINGUIx64.EXE.
But I can not see advanced menus.
I thinks it’s because it have TWO level of Advanced. I don’t know how to show the second level menu.
You can see th pictures attached.
And the Chipset menu has two. Only the first one is showed.
I’ve attached :
1. picture for the issue of 2 level of Advanced Menu
2. picture for the issue of 2 Chipset Menu
3. Official ROM
4. My MOD based on th Offical ROM
this BIOS is very likely to another link in this forum

I can use RU to modify.
@BDMaster Can you help me ? Or can you tell me how to deal with this.
Thank you very much
EDIT:
@BDMaster It’s very simmilar to the ONE you done for HDR-XC-laptop. Can you help me ? Or just tell me how to do.
I’ve tried to modify BIOS via RU for hackintosh. It works good.

Unpack and rename the bios mod like you prefer and flash it at same manner …

OK. Maybe disable VT-D is not needed.
I’ll try OSX later. Now I’m in windows.
@BDMaster After flash the 2nd ROM, the VT-D menu and the menu above it are gone.
OK. I’ll try later when back home.
Done!
Thank you very much!
