after a coldstart your hint worked.
Is there a possibility to pass manage this by udev?
modem-manager uses an enviroment variable and is triggered itself by dbus.
So it seems to be difficult in the first place.

The environment variable is only there for testing.  Once we have a
positive test, we can tell ModemManager that the 8790 is OK to do this
for everyone.

Once you have access to the notebook again, can you stop MM the normal

mv /usr/sbin/modem-manager /
killall -TERM modem-manager

and then run MM like this?

MM_SIERRA_APP1_PPP_OK=1 /modem-manager --debug

and attempt a connection?  Older Sierra devices allow PPP on the APP1
port (ttyUSB4 on your device) but unfortunately we have to whitelist
that.  It's actually impossible to test which tty accepts PPP on most
Sierra devices, so we really have no idea.  For examply, my C885 and
USB306 allow it, but none of my (four) 8775s or my 8781 allows it.
