Does the doctrine of the procession of the Holy Spirit from the Father admit of any change or supplement?

In this doctrine, the Church repeats the very words of Jesus Christ, which are the exact and perfect expression of the truth. Secondly, because the Second Ecumenical Council, whose chief object was to establish the true doctrine of the Holy Spirit, set it forth in the Creed; and the entire common union of the Churches of God has acknowledged this so decisively that the Third Ecumenical Council (Ephesus, 431), in its seventh canon, forbade the composition of any other Creed.

For this reason, St John of Damascus writes:

Of the Holy Spirit, we both say that he is from the Father, and call him the Spirit of the Father; while we in no wise say that he is from the Son, though we call him the Spirit of the Son. (St John of Damascus, Exact Exposition of the Orthodox Faith, I.8)
