Yes.

Acceleration measures the rate of change in velocity. So velocity can still be increasing even while its rate of increase goes down.
For example, suppose you are driving a car, starting from rest. You press down on the gas pedal as hard as you can, then let up slightly. The car’s velocity increases the whole time, but the acceleration in the second time interval is lower than it was in the first time interval (i.e., the acceleration decreased).
