How to disable IO buffers out of netlist verilog model

Hi,

Following is a description from the .vo file generated after Fitter Implementation.

We do not wan't the IO bufs to be implemented (its causing issues in GLS)

Is there anyway to not to implement IO buffers in .vo generated ?

stratixiv_io_obuf \DQ_OUT[0]~output (

.i(altsyncram4|q_b [1]),

.oe(vcc),

.dynamicterminationcontrol(gnd),

.seriesterminationcontrol(14'b00000000000000),

.parallelterminationcontrol(14'b00000000000000),

.devoe(devoe),

.o(DQ_OUT[0]),

.obar());

Thanks
