How can I disable gpio_bd pins?

The reference design for the Xilinx zc706_system_constr.xdc file defines the gpio_bd part to the various DIP switches and LEDs. I want to change some of these ports, as in assigning a different port to the LEDs.

 

The line for the assignment is set_property -dict {PACKAGE_PIN Y21 IOSTANDARD LVCMOS25} [get_ports gpio_bd[7]] ;

 

If I try to change this to assign a different port to this pin, bitstream generation fails because now there is a floating gpio_bd pin somewhere without a pin assignment. How can I disable that pin so that this error isnt thrown?
