I am trying to disable the "claim shell" mode of my MacBook running High Sierra ie. I want the computer to sleep when the lid is closed even when it is connected to power and an external monitor.

After disabling SIP I was able to edit the com.apple.Boot.plist file and add Kernel Flags iog=0x0 as I have done is previous OSs, but the setting doesn't appear to work in HS. Also
sudo nvram boot-args=iog=0x0 from (recovery mode) terminal writes the entry, but also has no effect.

Anyway to achieve lid close - sleep with external monitor and AC power in HS?
