This is the issue here. It shouldn't say DHCP, it should say "static",
because the WWAN network interface of all the new 5G modules are
always in raw-ip instead of 802.3, and therefore MM should fallback to
request static IP addressing instead of DHCP.

Please try to backport the following fix:
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/a8fd33ebaa80a0844c375fdb39173736d18f71cb

I really haven't spent much time backporting 5G related fixes to the
1.12 branch, because they will all be released together in 1.14 soon.
