EdgeTX and the RF Module can be updated directly from the SD card, without having to use EdgeTX companion. 

Remove the SD card from the transmitter and insert it in to a card reader on your computer.

Or connect the transmitter to your computer via USB, and the SD card will appear as a removable drive.
