Living/Garage wall and spray foam install question

I called to get some estimates on spray foam insulation and asked how they spray the foam for the common walls between the living area and the garage. They told me that the drywall is installed in the garage first and then they spray the foam. Drywall guys don't want to start the garage and wait for the spray foam guys to do the rest. Anyone have suggestions on how to get this done? I thought about using some of that 1/4" fan fold foam board to put on the garage side of the wall and have them spray the foam on that and then the drywall can be placed over the fan fold board.

Need more info.
Is this a new constructed house, or a garage being added to a house?
If I was going to make a mess with spray foaming a wall I'd want the mess in the garage not inside the house.

Sorry, new construction. All I have up now is the framed walls. Garage is attached.

Don't use the fan fold board but if you want some rigid board, that should work.

Faced, on garage side only- Fig.3-41;

ADA the drywall on garage side to keep the hot moist air from condensing on the cold studs (R-1.25 per inch) from AC;

PS. do the lid if living space above, Fig.7;
