That's a *USB modeswitch* rule, not installed by udev. The USB
modeswitch project will always prefer MBIM if possible, because it
requires less vendor-specific things to make things work. E.g. your
modem could be managed by libmbim+mbimcli right away if it was running
in MBIM mode.

Would you be able to post that new udev rule as a merge request?

modem-manager-gui is really a different project that makes use of the
ModemManager APIs, it's not maintained here. Although I'm not sure the
developer is around in the mailing list?
