Disabling one A/C duct/vent

Hi Everyone. I'm trying to turn off just ONE vent/duct/outlet (whatever it's called) in a one-story house that has central HVAC. I've closed the vent and closed the flaps, and it's still too cold in that room when the AC is on. Is there a way of simply and safely disabling or whatever it should be called ONLY that one duct/vent/etc.? -- without risking any damage to the rest of the system or the house, for that matter--and in such a way as it can be fairly easily re-activated when needed. Thanks so much for any thoughts on this. Bob

Are there any other registers in the home that could be opened more to help relieve the pressure on that one?

Welcome to the forums.

When you closed the register... did that stop the airflow from that register ?
If it did then it's coming in from the hallway.

Is there a return in that room ?

That duct may have a damper between the grill and the unit.

They make magnetic covers for them.
