CDC ACM driver for UEFI

I'm new to UEFI development.

So far, I have learnt about UEFI shell, build procedure and application basics.

My task is to communicate to a custom board from UEFI using uefi app through a USB cable from the PC (usb serial).

Currently, the PC is booted to UEFI shell and connected the board through serial cable and I type devices command, I see that the board is listed as

344 : CDC Abstract Control Model (CDC)

and

345: CDC ACM Data

Please help me to understand how I can proceed? And what works I need to do in order to detect my board as Serial port?

Is there any uefi driver available for this?

If I need to develop the uefi driver, please help me on what would be the starting point?

I haven't seen anyone develop a CDC driver yet, but there is a FTDI driver that could be used as a starting point.
