That's not perfect but I created a shell script based on https://docs.modalai.com/qgc-via-adb/ for the drone configuraiton.
For my PC configuration, I created an udev rule to force an interface name since usb0 is renamed in "enx******". My udev rule can only work with my drone (I think). To define IP address, I add a conf file in /etc/systemd/network/
I have only tested on my linux and it works perfectly :
#!/usr/bin/env bash
set -euo pipefail
