Can balena sound be installed on top of RaspiOS

I was able to install an image with balena-sound ‘one click’ and it worked, somewhat. I would like to install it on an already running RPiOS install. Is that possible? I would like to have direct SSH access to it as opposed to the VPN web interface. I find it laggy. If it is possible, is there a recipe or outline as to how to do it?
I tried RPiOS bullseye and iwd works, but nmcli does not. I then went to buster and have it up and running with nmcli functional as the networking component. iwd soes not work, though wpa_supplicant does.

Hi, if you like to use balena without the dashboard, we provide the cli for interfacing with your fleet. You can also directly ssh with a simple balena ssh command with the cli. Documentation can be found for that here: SSH access - Balena Documentation, Other than that, you can try and fork the balena-sound repo and modify it to work on RPiOS but I suggest trying the cli first for convenience
