If they were fitted but are not to spec, a local shop can do this, or you can have your seller get an authorization to send them to Titleist. The shipping cost will likely outweigh the cost of getting it done locally. The downside is this voids the warranty if done locally. The lie adjustment should not be attempted at more than +/- 2 degrees, Titleist suggests the plating on the hosel may crack.

Titleist's Custom Options Guide indicates lie adjustment up to 4 degrees upright for 718 AP1- same for all 718 iron models except the CB and MB models.

Cathi, at Titleist has confirmed that the 4 degree upright is from bending a 2 degree upright club so Don is correct in his 2 degrees maximum adjustment.
