Where can I get a schematic of the SIM7080-Modem used in the LilyGo-T-PCIE?

We are considering whether we can use TTGO T-PCIE ESP32-WROVER-B to perform MQTT communication with AWS IoT core and HTTP communication with an application server.
AWS IoT and the application server do not need to be accessed at the same time, but only need to be able to communicate alternately.
Is it possible to use the LilyGo-T-PCIE library to perform such a process?
