Could you please run ModemManager 1.10 with --debug and post the output here?

$ sudo systemctl stop ModemManager
$ sudo /usr/sbin/ModemManager --filter-policy=STRICT --debug

Could you also put the full "lsusb -v" output to see the full device layout?

MM 1.10 is using these port type hints for the LARA-R2 modem, maybe we need to update these:

# LARA-R2 port types
#  ttyACM0 (if #0): primary
#  ttyACM1 (if #2): secondary
#  ttyACM2 (if #4): tertiary
#  ttyACM3 (if #6): GNSS Tunneling (ignore)
#  ttyACM4 (if #8): SIM Access Profile (ignore)
#  ttyACM5 (if #10): Primary Log for diagnostics (ignore)
ATTRS{idVendor}=="1546", ATTRS{idProduct}=="110a", ENV{.MM_USBIFNUM}=="06", ENV{ID_MM_PORT_IGNORE}="1"
ATTRS{idVendor}=="1546", ATTRS{idProduct}=="110a", ENV{.MM_USBIFNUM}=="08", ENV{ID_MM_PORT_IGNORE}="1"
ATTRS{idVendor}=="1546", ATTRS{idProduct}=="110a", ENV{.MM_USBIFNUM}=="0a", ENV{ID_MM_PORT_IGNORE}="1"
