It's still true in Bullseye, but the implementation has changed
somewhat.
Instead of /lib/udev/rules.d/73-usb-net-by-mac.rules now systemd uses
/lib/systemd/network/73-usb-net-by-mac.link.

A straightforward approach would be to learn the actual name of the
device via "ip a"/"ifconfig -a", and then using that name in /e/n/i.

systemd.link(5), systemd.net-naming-scheme(7).
The keyword you need is NamePolicy=mac.

That could mean anything. Please show the output of "ip a".
