Brent,
First, that is not "firestopping", that is "separation". It is not even a "fire rated ceiling".
Question: Can the ceiling drywall be omitted if a sprinkler system is installed?
Nothing says it can be eliminated.
Besides, why would you want to?
That would expose all the insulation underneath the floor above to the garage side, and, it would also increase (make if much more difficult to eliminate or reduce) air infiltration and exfiltration.
