Bypass valves...flow restricters...new pumps...
People, this is a two gallon aquarium....8 x 8 x 8 inches...with a full length filtration chamber that takes up 25% of the width of the tank. Even a 10x per hour turnover is only 20gph. Pipe simply doesn't come small enough to reduce the output of a pump to a level suitable for this application. And any added hardware sounds frankly ridiculous in this microscopic volume.
A $10 air pump solves this problem. Or...maybe even try cutting a hole or holes in the return pipe above the pump so that most of the flow escapes into the filtration compartment with only a small fraction making it into the tank itself. I think even this will likely be squirting water all over the place.
Kill a mosquito with an appropriate tool...i.e. a flyswatter. Using a sledgehammer, a computer-guided missile or a bazooka is ridiculous (and probably unworkable) overkill.
