Esp32 LTE module without at command

I am trying to use LTE module for esp32.
looking for information
Most of them connect with uart and use mqtt with the at command.
I thought I could do that.

By the way, I came across a video of the TTGO SIM7600E-H Module ESP32 module.

TTGO uses esp32's mqttclient instead of uart and at commands.
Make a connection. like wifi

If the lte module connected to uart is recognized as wifi like ttgo,
Is there a similar way to use usb modem?
