No Codec in the prologue, but there's a lot of prologue-related stuff in R-01. Your only support in the prologue is Boris who talks to you in real-time only.

I think by equippable he means that it's perhaps modular or something, so you could detach the outer layers or perhaps just swap out the limbs for less fighty models if you're not in combat. Though you see Raiden's left arm is flesh and blood when Sam cuts it off, so it might be some sort of biomechanical tech with the outer layers designed to plug in on top of the inner human-like ones. We know his lower jaw isn't his original either.

It's pretty clear from the discussion in the game that most cyborg bodies are permanent and the alterations not easily reversed, including Raiden's new one. Probably a lot like Frank Jaegar's one, hence them pointing out they don't call that kind of work an "exoskeleton" anymore.
