I would like to use a 32 bit wide synchronous slave FIFO interface with my FX3 circuit. This reserves a large number of pins.
Before the slave FIFO interface is put into operation, I would like to borrow two or three of these pins (marked GPIO) in order to have enough pins to configure my FPGA. Can I temporarily configure these pins as Simple IO, on the fly even after the GPIO-2 configuration data has been loaded? Or does the GPIO-2 configuration data override?

Yes. You can do that.
Initially for configuring the FPGA, you can use few GPIOs from the slave FIFO interface and once after the configuration is done you can re-load the GPIF descriptors to use the GPIF as slave FIFO interface.
Thanks,
