Use other GPIOs for NSS, pull them low before each SPI transaction, back to high again when done.

Thank you very much for the prompt reply. Can I use any of the I/O pins for NSS or is there any particular GPIO pins for the same?

I have one more question that, once I connected the GPIO pins as NSS, later I should control these pins using software. Am I right or not?

Yes, you have to control these pins "manually":
GPIO LOW
do SPI stuff
GPIO HIGH
