The writer of Spider-Man: No Way Home has revealed in an interview that, there was going to be an alternate entry for Andrew and Tobey in No Way Home.
There was going to be a secret character(America Chavez) in no way home, who was going to help Tom's Spider-man in bringing another universe Spider-man for fighting with villains.
This idea was dropped, already no way home contains lot of characters and by introducing a new character it may cause a confusion in a normal audience.
America Chavez going to be in Doctor Strange: Multiverse of Madness. We have seen her with Doctor Strange across the trailer this shows she is going to have important arc in this movie.
Who is America Chavez?
America Chavez is belongs to different universe, she can open portals across the multiverse. Also she is a multiversal character that's why she is in Doctor Strange, because Doctor Strange: Multiverse of Madness is all about Multiverse. In this movie we are going to explore MCU's Multiverse.
