Jesus was and is eternally God, not a created being!Absolutely.
To have a "sin nature" you have to be created by a Father, who has it, himself.
Jesus was created by the seed of God, the Holy Spirit.
The Father of Jesus has no sin, has no sin nature, so, this Holy Spirit SEED that is Holy, created Holy Jesus who had no sin nature.
Jesus is the 2nd Adam, created with the same Spirit that was "One with God" as the 1st Adam had, before he rebelled and gained the loss of his righteousness, which is to be "fallen" or "adamic".
When we are born again by the same Spiritual Seed (the Holy Spirit), that caused Jesus to be born with no sin nature, we arrive back to the original righteousness.......same as Jesus's righteousness.........we possess "the gift of righteousness".
