You can't alter the player character's perks and stats in the prologue, but you will be able to get it in the game later (once that part is made)
(I just realized I forgot to ask) But when might that part be made? If you have a general area of time.
Depends on what you are asking about. I expect the levelling system to be fully completed within a month or so, but making the actual skills and the encounters that use them will be an ongoing process
