I know you don't want PPP in your setup, you have made that clear. I'm
not arguing with you about that. I get it. You don't want PPP.

Now, the way to fix that should be by making sure ModemManager gets
notified of the QMI/NET port before it creates a modem object only
with TTY ports. I understand that you don't like this approach, but
ModemManager doesn't receive a fixed list of ports to work with, as
many other modem management setups. MM tries to dynamically adjust to
what it finds, and that is a core feature of ModemManager that is not
going to change.

So again, and don't hate me for repeating this, if MM gets notified of
one single AT capable TTY port and nothing else, it will default to
use PPP. If you don't like that, please patch your ModemManager to fit
your needs. Or try moving to uqmi, which requires you to specify which
is the cdc-wdm port path explicitly, although that approach has its
own problems, but maybe not the ones you're worried about.
