Datasheet link I am unsing full duplex RS485 feature IC.
Please confirm below
To use this IC in half duplex mode I need to short Pin B to pin z and Pin A to Pin Y.
Since thease pins are internally not shorted ( beacuse it is full duplex feature IC).

You are correct -- Y to A and Z to B is what you need to do for a half duplex app -- you can also connect DE to /RE on the other side.
