I don't have an answer, just sharing my thoughts...

I think the ik40 Alcatel dongle sets itself like the default gw and dns,
and till the default bearer (data connection) on the dongle is not
activated it will redirect all dns queries and traffic on its own
embedded portal (so each dns name will be resolved to the private IP of
the dongle).

Seems the dongle is of type Remote NDIS (RNDIS), I don't know much about
the control interface of these devices...
Probably the device can be controlled from the embedded web server, so
from that, one can setup and tear down the data bearer (data connection)
via the web interface. This is what you are doing on the ik40.home site
I guess.
I'm not sure if there is any other supported method to switch this on
and off: can you control it directly via ModemManager?

Otherwise one can probably setup a custom solution (as should be
targeted on the specific web interface available in the embedded
web-server) with curl and dispatcher scripts in order to switch the
dongle connection on/off when NM activates/deactivates the connection
with the dongle: NM connection manages the IP connection from the host
to the dongle, but the "data connection" (the data bearer) from the
dongle to the Internet requires a separate management.
