SNAC never shipped with the OS, but shipped with SQL Server or SSMS.
If you have the install media for SQL 2019 or earlier, you may be able to install SQL Server Native Client alone, but I am not sure.
If you have not, you can find old versions of SSMS here: https://learn.microsoft.com/en-us/ssms/release-notes-ssms#previous-ssms-releases. If this page is to believed, SSMS 18 or older is needed.
