A small #starfield trick you might have missed

When in space combat, press LB to get to the aiming interface.

From there use LB and RB to navigate and select the ENGINES.

From now on you will only shoot at the engine.

If you manage to destroy the engines without destroying the ship, it became stationary.

You can now go near the enemy ship and press X to dock.

Now enter the ship, kill everyone and steal it.

Enjoy.
