No, that won't work.  Unless someone has fixed this up, there is no
automatic use of the "QMI over MBIM" feature. You need to explicitly
enable it both at build time and runtime:

 libmbim:
   ./configure --prefix=/usr; make; sudo make install

 libqmi:
   ./configure --prefix=/usr --enable-mbim-qmux; make; sudo make install

And then run the command with '--device-open-mbim' (and I recommend
using proxy too):

   qmicli -p -d /dev/cdc-wdm0 --device-open-mbim --dms-set-fcc-authentication

If you run the command like that, then it shouldn't matter if
ModemManager is running at the same time.

Yes, this is unnecessarily complicated and error prone. I just didn't
implement all the user friendly parts in my quick-and-dirty first hack.
Feel free to fix :) At the very least, qmicli should do some sanity
checking and return legible error messages when they fail.
