Lock Screen defaults on S10 running current FW

Hello,
Can anyone help me with setting the options that are populated on the lock screen of a S10? When a user locks the shared terminal the default option that is selected is
“Unlock Password”
below that we have
Sign-off from account “username”
Shutdown the system
Restart the system

On our shared terminals users are locking out the user account that was logged in so i want to set the default action to “Sign-off from account “username”

Thanks,
