Specify fewer input/output ports in the top level of the hdl file or schematics.

Synthesis tools have nothing to do with the number of IOBs. The number of I/Os is determined by your design. One way to reduce I/O count is multiplexing.

Re-phrase the question, because you cannot remove I/O port which exists in the design. Because it's like asking "can i use 16K RAM block without actually consuming it?"
