Writing a udev rule to ignore device by ModemManager worked for me:

/etc/udev/rules.d/55-bluetooth-drone-NoModem.rules
KERNEL=="rfcomm*", ATTR{address}=="xx:d3:xx:00:xx:xx", ENV{ID_MM_DEVICE_IGNORE}="1"

And reloading rules:
sudo udevadm control --reload-rules

So I connect to device as root
sudo rfcomm connect hic0 XX:D3:XX:00:XX:XX

and then I am able to use it as regular user from dialout group
