You can compile ModemManager with --without-mbim; or, as Bjørn suggested
load the 'cdc_ncm' kernel driver with 'prefer_mbim=N'.

Anyway, when using MBIM, ModemManager will not request the network
interface details to be set with DHCP; instead it will explicitly expose
in the bearer interface which IP details to use (and NM will read them
and apply them in the interface, if using NM).
