Is it possible to make the USB-UART interface look like a MIDI class compliant device

Many dev kits come with a USB-UART interface, is it possible to make it look like a USB MIDI class compliant device so that it would automatically be detected as a MIDI device when plugged into a computer's USB port?

If so, where would I start to find out how to do it?

I am particularly interested in the DE1-SoC and DE0-Nano-SoC's USB-UARTs, but information on how to get it to work on the DE0-Nano-SoC's USB-OTG interface or on any other dev kit's USB-UART interface would also be appreciated.

Thank you.
