If you want to "stick" to spacetime, there must be a reference frame that is somehow different from all the others. There is presently no experimental evidence for any such frame, despite a century or two of searches by very clever people.

If it's a time gradient that causes an object to accelerate, then if you can apply a reverse gradient that would just cancel out the forces. But yes, one would need to first figure out how to do that without an equivalent amount of mass on the other side, if it's even physically possible. Here's a stupid idea that's based on my definitely flawed understanding of relativity: If having high relative velocity causes time dilation, then wouldn't spinning a disc at relativistic speeds cause that same time gradient? Maybe we just need 99.9% c rad/s fidget spinners to float in the air just like bricks don't.
