Edge-V Extra UART?

Is it possible to create a UART port on the Edge-V similar to the VIM3’s UART3 at /dev/ttyS3? I see in the Edge V schematic there is a UART0 which is used for SPI3 on pins 15&16. Is there a way to write a device tree to add this feature? Could it be done with fenix, or is there a hardware problem with doing that? (Could be any 2 pins, don’t care, just need UART.)

1.It cannot be configured as uart.

2.There is also no other pin in 40pin that can be configured as uart.
