Cyclone 4 I/O pin configuration

I am using Cyclone 4 FPGA (ep4ce15) for my design. During the power ON all the I/O pin are getting pulled to high through internal pull up. is there any way , i can pull down all the I/O pin to ground or tristate at power on?

    No, you can only change the state of the pins after configuration.
