If there was a better solution with usb_modeswitch or whatever by changing the product ID by an other one, It would be much easier.

Well, I found out how to change mode on FreeBSD:
usbconfig -d 1.2 set_config 0 # 0 or 1 for 1 or 2
I'll keep using mode 1, like Ubuntu does.

I'm currently working on building a new kernel following this page:

Thank you for your ...

This module does not have an install mode so doesn't need modeswitching.

The module has 2 configurations to choose between, config #1 has usb interfaces for dial-up modem (ppp) , direct ethernet adapter (cdc_ether), and gps/gnss.
Config #2 has usb interfaces for direct ethernet adapter (cdc_mbim ...

Here it is:

Actually, ue0, an Ethernet interface is appearing on FreeBSD:

Hi everyone,

I'm looking for a solution to get this module working on pfSense 2.2.4 which is based on FreeBSD 10.1:
