Related to this question and this question but with Pipewire not pulse audio (unless it is the same, but pacmd doesn't work):
How do you set the default output device (the radio button below) at the command line?

you have to use pactl.
pactl --help says:
...
pactl [options] set-default-(sink|source) NAME
...
and you can get the name examining the output of:
pactl list sinks
according to the arch-wiki it seems that, with the package pipewire-pulse, even though pulseaudio is not running or installed, the command pactl is usable.
I can confirm this works on one of my debian-based machines (specifically the Librem5 with mobian).
As an extra:
pacmd will throw an error:
No PulseAudio daemon running, or not running as session daemon.
