script to turn off/disable specific monitors on a multi-monitor system

relative information: i have two systems that share a monitor. one system is a laptop for work that i must log in and out of, the other is my personal  system that has a power save mode turning the monitors off after 10 minutes of inactivity.

the problem: work laptop, when logged out, has login screen that outputs to all connected monitors all the time (no power save mode for this screen).

desired fix: i already have log-in and log-out scripts, so i'd like to add a script to the logout to disable the external monitors and a script for log-in to enable the external monitors (and adjust their relative position/placement). i've attached an image to show the configuration of the screens in their enabled state. screen 1 is the laptop and screen 2 & 3 are what i need to disable.

i have found around half a dozen forum articles that are about a decade old. most, if not all, suggest actively running scripts to keep the monitors off. i believe this to mean their effect would be lost once the laptop is logged out of as the script would end with the session.

If you turn off extended displays (using Winkey+P for example), and back on, does it remember your last layout correctly?

If so, perhaps simply calling displayswitch.exe from your logon and logout scripts will do the job?
