Usually Samsung does bring some New Flagships features to Older Flagships after couples of months but, it isn't always sure if Samsung will do that or what features Samsung might add to Old Flagships from New One. So we'll just have to wait and see.

Hi @Invester, I hope you are doing well.
There is no official word as to if and when this feature will be available on older Samsung devices. Your best best is to keep an eye on your carriers support page and follow Samsung related news outlets such as Sasmung Mobile's Twitter (@SamsungMobileUS).
As mentioned, Samsung tends to backport these features but as for now, this feature isn't gurenteed to make it as of now.
I hope this helps!
