Bios Mods -The Best BIOS Update and Modification Source

Good day, I would like to enable virtualization technology, enable video memory size allocation and disable FN hotkey so that my function keys work without turning on media player all the time.
I used Universal BIOS Backup ToolKit 2.0 to extract the file. Link to extracted file is at bottom of post.

Bios file

I am just wondering if this bios is too difficult to modify. I don't see any upgrade bios from the manufacturer for this computer.
