pmod connectors on zc706 and FMCOMMS2

I am trying to build a design on the ZC706 Evaluation board using the FMCOMMS2 radio. I see that many of the PMOD connectors are used in the design (hdl/system_constr.xdc at master · analogdevicesinc/hdl · GitHub ) Some of  them are specified below.

set_property -dict {PACKAGE_PIN AJ21 IOSTANDARD LVCMOS25 PULLTYPE PULLUP} [get_ports spi_udc_csn_tx] ; ## PMOD1_0_LS
set_property -dict {PACKAGE_PIN Y20 IOSTANDARD LVCMOS25 PULLTYPE PULLUP} [get_ports spi_udc_csn_rx] ; ## PMOD1_4_LS
set_property PACKAGE_PIN  AA20 [get_ports tdd_sync]
set_property IOSTANDARD LVCMOS25 [get_ports tdd_sync]


But when I connect the board, I use only the FMC LPC port right?

when and why are these other pins used in the design? There is for example the tdd_sync singnal also connected to one of the PMOD pins.


I wanted to use these PMODs for other user IO operations. Is this possible?
