Is possible to connect ESP32-S2 to a 4G USB dongle and connect to the internet? （not using WIFI)

This is probably technically possible. Depending on the exact USB device it may require some additional driver support which may or may not be supported in ESP-IDF.

Note that you can connect an ESP32 to a serial cellular interface right now, we have an example with support for the Quectel BG96 LTE module: https://github.com/espressif/esp-idf/tr ... pos_client - and other modules which support PPP over Serial should be easy to integrate.

Thank you. I ported the PPP over Serial to EC20 and it was working perfectly.
Looking forward to seeing rndis driver support in ESP32-S
