No. Acceleration is change in velocity. That's what it is measuring. If velocity is not changing, acceleration = 0.
No experiment can distinguish between gravity and uniform acceleration, so if acceleration is what it's measuring, it can't possibly tell the difference between 9.8m/s^2 of acceleration and Earth-normal gravity. Indeed, just as Special Relatively is based on the fact that rest and uniform motion are the same thing, General Relativity is based on the fact that gravity and acceleration are the same thing. If you are sitting still on Earth's surface, you are undergoing 9.8m/s^2 of gravitational acceleration. In order for the accelerometer to read zero, you would have to be in free-fall.
