Please note that the reason to use PPP is not that MM sometimes
prefers it over QMI+NET. If PPP is being used, it's likely because the
QMI port failed to be probed successfully, so AT+PPP is the only
option left. The failure in the QMI probing could be a limitation of
the probing logic, or the modem firmware getting fully stuck, or
something in between (e.g. maybe a given modem boot took longer than
usual and we failed probing while waiting for it to work properly).
Debug logs will tell you in detail why PPP is chosen instead of
QMI+NET.
