BG95-M3 How to enable AUX AT port

IoT Modules LPWA Module

Hello, I’m trying to make oFono work with BG95-M3, but it needs a second port (AUX ATt) to send and receive AT commands. There are four USB interfaces detected by my system. Only one of them (ttyUSB2) can accept AT commands. Is there any way that I can enable another USB interface for AT commands?

My firmware is

AT+QGMR
BG95M3LAR02A03_01.009.01.009

for usb-uart , only the ttyusb2 can send at ,

but the physical uart （ main uart ）can send at, even so , we can use multiplexer protocol simulate maxium 4 uart channel

Unfortunately, we cannot use the main UART for our product. Is there any plan to enable second UART over other USB interface in the near future?
