There isn't any other option or alternative to emulate that? I mean, Protect is the only way? Thanks again!

EDIT: I mean, unless Vader was prepared, use Protect out of turn is a light side option.

Not really, unless his cybernetics count as a weapon capable of Reflect. But Protect is the best way to emulate that effect, I would say.

Given the scene in question, and how Vader had set all of it up to his specifications, he was definitely prepared for getting shot at.
