Use non-GPIO pin to capture external rising edge?

Hi,

In designing the PCB board, we mistakenly used a non-GPIO pin to connect to an external signal:

and we wish to somehow configure this pin so that it could capture the connected external's rising edge and generate an interrupt for each.

Is there any way to make

1. UHPI_HD[5]
2. UPP_D[5]
3. PRU0_R30[13]
4. PRU0_R31[13]

serve this purpose?
