Actually its a question born out of spiritual ignorance. Nobody knows when they are actually born of the Spirit, which is when He initially indwells, for Jesus says its a mysterious sovereign work as te wind Jn 3:6-8
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7 Marvel not that I said unto thee, Ye must be born again.
8
The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
When was John the baptist indwelt of the Spirit ? For he actually was Lk 1:15
For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and
he shall be filled with the Holy Ghost, even from his mother's womb.
Now one of the evidences of having the Spirit of God indwelling is believing the Truth of the Gospel which you dont believe and actually speak evil of it calling it calvinism with hate.
Actually the bible speaks is quite clear of when one is born of the Spirit. It is when they believe.
Act 10:44 While Peter was still speaking these words,
the Holy Spirit fell upon all who heard his message.
Act 10:45 All the circumcised believers who had accompanied Peter were astounded that
the gift of the Holy Spirit had been poured out even on the Gentiles.
Eph 1:13 And in Him, having heard and believed the word of truth—the gospel of your salvation—
you were sealed with the promised Holy Spirit,
Rom 10:9 that
if you confess with your mouth, “Jesus is Lord,”
and believe in your heart that God raised Him from the dead,
you will be saved.
Now if you want to say we can be filled with the Holy Spirit that is biblically different.
John was filled from his birth for service
Luk_1:15 "For he will be great in the sight of the Lord; and he will drink no wine or liquor, and he will be filled with the Holy Spirit while yet in his mother's womb.
Elizabeth and Zacharias were filled and praised God. Luk 1:41 & Luk 1:67
Those in the upper room on Pentecost Act 2:4
Peter when he spoke to the Rulers and elders of the people! Act 4:8
Paul and the apostles were filled with the Holy Spirit Act_13:9 & Act_13:52
And we can't forget that Jesus was filled with the Holy Spirit "Then Jesus, being filled with the Holy Spirit,..." Luk_4:1
Being born of the Holy Spirit is salvation being filled with the Holy Spirit is for service to God.
But I can excuse your not knowing this as it is born out of spiritual ignorance.
The reason that I speak out against calvinism is because it distorts the truth of God as it's foundation is from the 4th century when augustine brought pagan philosophy into the church. So why would you think any Christian would not hate that?
