This is a tough question, because there are interpretations that stretch the concept of respec. In short, no, there is no respec option.
A close thing: From the title menu, click PLAY, then new game (top), pick the character that you want to respec, default player setup, and the last chapter available. E.g, at chapter 18, the game generates a character with a crowbar and machete, both white-rarity, $10000, at level 32, and with no skill points spent.
What if, instead of choosing "default player setup", I choose a character save file? This creates a new save. The new save will use the chosen character data. The character will be set at the chosen chapter's story progress. This does not affect items, skill-points, side-quests from before the story point, blueprints acquired, etc..
If you are not opposed to the use of exploits to regain lost progress in the face of the lack of a better respec system, grinding levels is easy Sveti with the Time for Booze continuous event (side-quest), with duplication.
