ESP ota update with LoRa modules

Greeting Renzo, I have a project that used your EBYTE E22 LoRa module with using ESP32. Now here is what i want to ask: I will have several ESPs in an area and i want to update their softwares over the air with using LoRa modules remotely. Each ESPs will have their own LoRas for sensor measurements. I was thinking doing with WiFi since it already has a library for it but most of time they won't be connected on WiFi because they are away from me and they will be located at several places + i can't use Wifi reuter for each. Its costly. Is it possible to do firmware update with LoRa modules? Thanks.
