The voltage tables for configuring their registers mention range of voltages: 0.750 V to 3.55 V, 2. The constrains in electrical specifications say output voltage range to be different (buck7: 1.2 V to 1.5 V, buck8: 1.8 V to 2.1 V). Adjust the ranges to match the electrical specifications to stay on the safe side. Anyway these regulators stay at default value so this should not have effect.
