I am trying to read six differential signals on zybo z7-20 board. I could connect four of them to JA Pmod connector and rest i want to connect to JB Pmod Connector. So how to configure other two inputs to JB Pmod connector?

If you don't need the other two pins, you can just ignore them or use them for some other purpose.

Thank you for reply.
I have to sample other two signals too and hence can't ignore it. Is it possible to get it from any other pins of zybo? Is there any other way to sample other two signals without using external mux?

I don't follow what you are asking. The pins on the Pmod connectors are all independent I/Os. Each can be use for it's own purpose. Define the inputs and outputs that you need in your design and then map them to the pins on the device in a way that makes sense for the board you are using.
