Firmware request for RM500U-CN

Hello, I know that this is off topic but could anyone who owns RM500U-CN check their module if it support mbim mode using this AT command.

AT+QCFG=?

For me the mode 2 is missing which the doc said it was for mbim

+QCFG: "usbnet",(1,3,5) # <-- Here, 2 is missing

I’ve created a new thread but got 0 response so far.

Thank you in advance.
