I found solution by myself.
1. Boot ubuntu from USB device
- I used Ubuntu 22 LTS, generated by Rufus app.
- You have to temporarily disable Lenovo secure boot.
2. Send AT command using ModemManager
-> this command changes modem model type to DW5930e (probably DELL modem?) and it automatically opens COM port.
(Default AT^CUSTOMER value for Lenovo X1 carbon is 6)
3. Remove USB device and boot back to Windows..
- enable secure boot
- modem shown as COM serial device on device manager!
4. Connect modem with putty serial.
- 'COM3' port was used in my environment.
5. Send AT command
4G & 3G ONLY
5G ENABLED (automatic)
