That's your spin. Peter explicitly said be baptized in order to receive forgiveness of sins and the spirit. You're readinng into other less explicit scripture the exact opposite
“And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.”
Acts 2:38 ESV

metanoesate translated repent is an aorist imperative active, something you do. Have a change of mind.
baptistheto translated be baptized is an aorist imperative passive. Not something you do, but something done to you.
eis is into.
This seems more correct.
“Kefa answered them, “Turn from sin, return to God, and each of you be immersed on the authority of Yeshua the Messiah into forgiveness of your sins, and you will receive the gift of the Ruach HaKodesh!”
Acts of Emissaries of Yeshua (Act) 2:38 CJB

Its exactly the same thing that is said here:
“In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit,”
Ephesians 1:13 ESV
https://bible.com/bible/59/eph.1.13.ESV
“In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace,”
Ephesians 1:7 ESV
https://bible.com/bible/59/eph.1.7.ESV
When we believe/have a change of mind we are sealed/immersed into Christ by the Holy Spirit. When we are immersed into Christ we are also immersed into forgiveness of sins.
