Sorry for the late response. I was out of the region turning up a new site.

Makes some sense. But there must be some way to select mode in the
bootloader?

If this modem is going to end up stuck with pure PPP and therefore maxing
out at 25Mbps, then I'm not too concerned anyways since its use is rather
limited. I just wish I could figure out how to switch this thing to MBIM

Yes, it does have two AT ports.
However, once ttyACM0 gets tied up and times out after 10 command retries,
ModemManager removes the modem:
ModemManager[13213]: [1533754896.224557] (tty/ttyACM0) at port
timed out 10 consecutive times, marking modem
'/org/freedesktop/ModemManager1/Modem/0' as
I have been given a Fibocom L850-GL that seems to be stuck in NCM mode.
As I have not had any luck changing the mode back to MBIM:
ModemManager[25270]: [1533696762.104669] (ttyACM0): -->
'AT+GTUSBMODE?'
ModemManager[25270]: [1533696762.121517] (ttyACM0): <--
