Stratix IV Device IO standard

We are using Startix IV, in DE4 FPGA board. Currently the STRATIX_DEVICE_IO_STANDARD is set as 2.5V. I want to know whether 3.3V is supported?

On a different note, I need a clarification on the internal pull-up in FPGA. For the internal pull-up, am I correct to say that either we can enable it always or disable it always BUT the enable/disable is not programmable by register control internally in design?
