Windows 10: Auto-brightness in Windows 11

I have a laptop running Windows 11. Sometimes it will automatically dim the screen which I don't want as I want the screen to be always bright whether it's plugged in or on battery. In Windows SETTINGS > BRIGHTNESS there is no option to control auto-brightness, though I have found websites that instruct differently. Likewise, I can't see anything in POWER SETTINGS to change auto-brightness.What do I need to do to stop my laptop automatically dimming the screen?Web article that makes reference to functions that aren't on my version of Windows 11: How to Turn Off Auto Brightness in Windows

   • Toggle on "Use HDR" under the "HDR" section.
     
2. Enable Auto HDR:
