Since this question did not get closed as duplicate of Why would a GFCI trip on refrigerator circuit?, here is the most upvoted answer from that question that is very much on point in answering this question:
Bottom line: If the adopted codes in your area do not provide an exception for running fridges without a GFCI in your garage, the best you can do is add get someone to add a snubber if you want a legal installation.
Sure the fridge works great for you now without a GFCI in your garage, but will you remember to change out that circuit before you move? How about if the unfortunate/unexpected happens and you don't get that chance? Will the next homeowner think this is a general purpose GFCI protected circuit as it should be in a garage?
