How to disable Bluetooth on Raspberry Pi?

I noticed that several people have asked about how to disable Bluetooth on a Raspberry Pi, but I have not been able to find a solution. I came across some suggestions to modify the config.txt file, but the HAOS on my Raspberry Pi does not seem to have this file, or at least I cannot locate it. Can someone please help me figure out an easy way to disable Bluetooth? I have already removed it from my configuration.yaml file, but Bluetooth is still active, as it appears as a suggestion in my Settings → Devices & services section.
