How to disable Data Execution Prevention in DV8P on win 8.1

I cant find out how to do it
i have newest bios (v14) and saw option "XD" [different sources says thats DEP or 2cpu management] and set it to disabled and thats nothing changed the same situation when i combinating with BCEDIT and standard advanced menu in my computer and its always TRUE value in console when check it , i also tried set settings from windows with CLI>BIOS but i cant find any clue how set parameters 
there's any option to change DEP to disabled from CPU/UEFI/BIOS/MOTHERBOARD ?

or at least i had to download similar AMI BIOS and manual modify and risk break my device?

im first dump my settings and look fot XD and nothing founded so i loaded first option in program dump conf then dump my conf add cpuxdsupport=disable to my conf and save as exe but it still doesnt work

So i do some research and found function to disable DEP in BIOS and i marked it on screenshot but how to add this to menu setup ?

im also found that 

0xCD6B Setting: CPU XD Support, Variable: 0x54 {05 91 9B 00 9C 00 0D 00 01 00 54 00 10 10 00 01 00}
0xCD7C Option: Disabled, Value: 0x0 {09 07 E9 00 00 00 00}
0xCD83 Option: Enabled, Value: 0x1 (default) {09 07 E8 00 10 00 01}

and i think strings with start at {05 xx xx xx} are CPU linked 
my question is how to find out string which im supposed to insert to my modification?
maybe [tag:dell] give me a clue ? or BIOS file version without any data execution prevention i think i doesnt need this becouse of malwarebyte and im responsible user
