FYI I've discovered that this doesn't play nice with my monitor that supports DDC/CI control. https://github.com/xanderfrangos/twinkle-tray/ works though.
Thank you
To anyone looking to shut off a specific monitor and have it stay off until you physically push the monitor power button, it looks like there is a utility for it. Can even change settings by command line.

Brilliant, thanks for this. Windows is a bit weird when you mix and match displayport and HDMI monitors where windows will jump from the DP monitor to the HDMI one when you physically turn the power off both, so this solution with a bat file is preferable - even thought I also use Persistent Windows.

Also, thanks for the recommendation of Twinke-Tray @Shazib.
I'm having a problem using this powershell script on my Asus MiniPC PB60. It does turn off the monitor. I set it up in Task Scheduler to run when the machine is locked. Works like a charm. Trouble is that it seems to disable background processes, too. I'm using this machine primarily as an iTunes and HomeBridge server. But if I use this script, both HomeBridge and iTunes stop working with the machine locked. It also takes out the little utility that controls the UPS, which is connected by USB. As long as I don't use this script to turn off the monitor, everything works fine with the machine locked.
Any ideas? Is there a way to modify this script to turn the monitor off, but allow everything else to keep running?
First of all thanks to EugeneLoy and unknown for me the author of the command :-)
Today 2.6.2023 - it works for me. Conditions - Win10 22H2. Two monitors. Both displays are turned off one time.
Cheers.
