Gates usually open around then but that's mainly when they want to be sure all Y pax are in the gate area and boarding can start if the plane is ready.
T-20 is usually the hard limit on gate closure at DXB except in the case of the FCL A when they open boarding around T-20 instead!
However! If you haven't checked in yet and are originating DXB sometimes they deny access to airside at T-60.
