You can cut the top surface of the black plastic off with a knife or razor blade and it will reveal the torx female fitting in metal. A little plastic will remain inside the torx recess. Dig it out with an awl or sharp pointed object. You'll be able to turn them out after that with a 30.
I wouldn't want to rip the screws out as you most likely will damage the metal tab mounts or the plastic door mounting tabs that hold them in place. That would mean your door skins would be unmountable at some points.
