No. The will of God is entirely unchangeable because both the substance of God (Q9 A1) and His knowledge (Q14 A15) are entirely unchangeable .
The will of God, as it is the first and universal cause, does not exclude intermediate causes that have power to produce certain effects. Since however all intermediate causes are inferior in power to the first cause, there are many things in the divine power, knowledge and will that are not included in the order of inferior causes.
