Is there any evidence that μορφῇ θεοῦ (morphe theou) in Philippians 2:6 means the "nature" of God the Father? Is there a NT evidence and contemporary first century evidence that morphe is used as having the meaning of "nature?"

Is there any evidence that μορφῇ θεοῦ (morphe theou) in Philippians 2:6 means the "nature" of God the Father?

ὃς ἐν μορφῇ θεοῦ ὑπάρχων οὐχ ἁρπαγμὸν ἡγήσατο τὸ εἶναι ἴσα θεῷ, — SBLGNT

Several translations including the NIV render it as "nature":

Who, being in very nature God, did not consider equality with God something to be used to his own advantage; — NIV

While many others (e.g. ESV, NASB, HCSB, ISV, NET, etc.) render it as "form":

who, existing in the form of God, did not consider equality with God as something to be used for His own advantage. — HCSB

Is there evidence in the NT and/or contemporary first century literature that morphe is used as having the meaning of "nature"?
