Can I disable the default CLI screen output via HDMI on HAOS (Pi 4)?

I'm running HAOS on a Raspberry Pi 4 and using it to send HDMI-CEC signals to my TV. It works great, but I've run into a specific issue: the Pi outputs the default command line (CLI) screen to HDMI by default. Since I rely on the HDMI connection for CEC control, I can't simply unplug the cable.

The CLI screen itself isn't a huge problem, but it conflicts with my automation setup. I have a daily routine that restarts the system, which causes my TV to trigger "on" and display the CLI screen every day.

I thought about creating another automation to turn the TV off after the restart, but that’s not ideal—sometimes I stay up late watching TV and don’t want to be interrupted by the TV switching off or changing inputs.

It would be much better if I could just disable the HDMI video output/CLI screen entirely while keeping the CEC functionality active. I haven’t found much information on this specific use case, so any insights or workarounds would be greatly appreciated!
