You cant

It needs the hardware SPI port lines SCK,MOSI and MISO which is on aux3

In theory you could setup software SPI on any pins, but in reality it is far to slow and would use to many cpu cycles and thus it would cripple the ramps.

You can use any IO line as the CS... but that doesn't really help.
