RDS Custom for SQL support Always On for HA

Hi,  I have a question, is possible than RDS Custom for SQL with license Enterprise support Always On for high availability, because we need read replicas of this database.

If the answer is not, what options I have, to take advantage of my license because I have S.A. for SQL Server.

Note that when using AlwaysOn for HA (active-active) with SQL Enterprise, both active nodes must be fully licensed.

Hello.

Until the multi-AZ deployment feature was supported by RDS Custom for SQL Server, I think it is possible to use Always On because it was often configured to self-manage.  
Nowadays, the Multi-AZ deployment function is available, so I think Always On is rarely used.

> Amazon Relational Database Service (Amazon RDS) Custom for SQL Server now supports high availability by using block-level replication in a Multi-AZ environment. Previously, to enable high availability on the instance, you had to configure an Always On Availability Group (AG) between two instances. Setting up and configuring Always On requires planning and expertise. With the new Multi-AZ capability, high availability is simplified.
