How to remove interface wwan0

Hi all.
Has anyone already managed to uninstall the qmi interface (wwan0).
I have removed the qmi_wwan and cdc_wdm but they come back after a reboot for the qmi removal but no luck.

Please follow these instructions:
sudo nano /etc/modprobe.d/raspi-blacklist.conf
Add the following lines:
blacklist qmi_wwan
blacklist cdc_wdm
Save and exit
sudo chmod 644 /etc/modprobe.d/raspi-blacklist.conf

Now reboot your Raspberry Pi
