Terminal velocity is by definition the speed of freefall. If you employ engines, you can achieve any descent velocity, as demonstrated by space marine droppods and real-life ballistic missiles, particularly hypersonic ones.
Plenty of ballistic missiles make approaches to their targets under power, either to maneuver against the interceptors, or simply to pass the intercept envelope faster. You can see as much even if you watch the videos of the Iranian missiles arriving in Israel yesterday.
