@Ben Larew Thanks for reaching out on Microsoft Q&A.
Yes, you are correct. According to the Microsoft Learn article on cross-region replication of Azure NetApp Files volumes, Azure NetApp Files volume replication is supported between various Azure regional pairs and non-standard pairs.
East US and South Central US are supported under an Azure regional non-standard pair. You can replicate Azure NetApp Files volumes from Regional Pair A to Regional Pair B, and vice versa.
To create cross-region peering, you need to follow the requirements and considerations mentioned in the article on Create volume replication for Azure NetApp Files
Please check Requirements and considerations for using cross-region replication here.
