I was working on some Bluetooth improvements and noticed that bluetooth always starts during boot even though its systemd unit (bluetooth.service) is set to "disabled" and it's not turned on in Renderer Config.
I poked around a bit and was not able to find what is starting Bluetooth.
ETA: Here's what shows up in dmesg log
