Armament Haki has the ability to bypass the powers of a Devil Fruit user, touching the "substantial body" beneath whatever protection the fruit provides, such as the case of body-altering Devil Fruits such as Logia users. However, unlike seastone, it does not negate a user's Devil Fruit powers, allowing them to defend themselves, and continue fighting normally.
Example Armament Haki:
Although Luffy grabs Ceasar with Haki, the latter is still able to transform himself into his Logia Gas form.
Because of the Kairoseki handcuffs, Marco is not able to transform into his Phoenix form anymore. Moreover, he is not able to regenerate his wounds as long as the seastone touches him.
