It’s helpful only insofar as protein contains calories, and excess calories cause you to gain fat. But protein is an inefficient way to gain fat relative to dietary carbs and fat, not least because it is highly satiating.
If you want to gain fat through shakes, I’d highly recommend tried and tested double/heavy cream and or ice cream shakes. These are high in dietary fat, the most calorie dense substance on Earth and the most efficient way to get fat.
