2005 NEC...... I understand that a snap switch is allowed to be used as a disconnect for a detached garage being fed with a single branch circuit or a MWBC. Question....can a GFI receptacle be allowed as a disconnect? If not, what part of ART. 225 can I referance. Thanks for the help.

I don't see why a gfci dead front could not be used but the code does say snap switch.

Dead Front GFCI's can be used as controllers but not as disconnects. They are also not considered indicating and it can be hard to tell if they are on or off. If the power were off to the building because of another reason such as utility failure it would be impossible to turn the service disconnect off.

All of the GFCIs I have seen (limited) will still trip if the power is off when the test button is pushed.

Some of them will not trip with no power. Some of them will not reset with no power. It depends on the vintage mostly.
