I am now using Bookworm (2024-11-19), running headless, and because I need the Pi3b to be as power efficient as possible, I've disabled Wifi, Bluetooth and I am running the network across a wired cable.
In previous versions of the Pi OS, I used the tvservice to power down the HDMI, but I believe that isn't an option anymore.
I've tried ddcutil and that appears to just turn off the monitor, not the HDMI.
Any suggestions for the modern way to turn off HDMI after boot ?
