Absolutely
Most of the ufo's/saucers/spacecraft of unknown origin operate this way. It would logically be the most efficient way to space travel outside of actual teleportation/wormhole shortcutting (which they probably also use)
The Alcubierre drive principle is that a gravitational well is created upfront and a gravitational hill is created in the back, on which the craft rides the difference like a wave. It can be visualized like a continuous hill which the craft travels downward. In actuality it would be falling towards the well while also being pushed by the hill
The way these craft operate has been explained as them generating a field, a kind of a bubble around the craft which shields mass, in effect the mass is nullified compared to the outside of the bubble, there is still mass within the bubble but the gravitational distortion field causes discrepancy between it and the outside environment. The gravitational distortion also enables time displacement, whereas the time inside the bubble the craft is in is passing normally relative to the inside of the bubble, but outside the bubble the craft appears to be moving at immense speeds.
