Scriptable BIOS Option

I am provisioning some NEO Z83-4 Pro machines and would like to set all of them to automatically power on when AC power is present. I know there is an option to do this in BIOS setup, but it's a pain to have to do this for every machine I am setting up. Is there a script that I can use to automate the setting of this option when I provisioning these machines? Is this setting stored in NVRAM?
