Wio LTE Cat M1/NB-IoT Tracker Ublox firmware update

What’s the best way to flash new firmware for the Ublox module? I have the firmware and programmer from the ublox rep but I see on the schematic there isn’t an actual USB connection to the module. That means I would have to do it either over the air or through the host. Can I modify the module to do a USB update or any suggestions?

I got a method, but I haven’t tried it :joy:
