This should do it.
 

#!/bin/sh

CURRENT_USER="$(stat -f%Su /dev/console)"
plistFile="/Library/Preferences/ByHost/com.apple.controlcenter.plist"

defaults write /Users/$CURRENT_USER/$plistFile Sound -int 18
defaults write /Users/$CURRENT_USER/$plistFile "Screen Mirroring" -int 18
defaults write /Users/$CURRENT_USER/$plistFile Bluetooth -int 18

Hi Bro,

Thanks for the sharing. I tried; however, it is not working. 

Thoughts?

This one working :

#!/bin/bash

_user=`who | grep console | awk '{ print $1 }'`

sudo -u $_user defaults write /Users/$_user/Library/Preferences/ByHost/com.apple.controlcenter.plist Sound -int 18

sudo -u $_user defaults write /Users/$_user/Library/Preferences/ByHost/com.apple.controlcenter.plist Screen\\Mirroring -int 18

sudo -u $_user defaults write /Users/$_user/Library/Preferences/ByHost/com.apple.controlcenter.plist Bluetooth -int 18

exit 0
