SQL Always ON AG DR on azure VM using Async Commit.

Hi Team,

I've one requirement of creating a DR using SQL Always ON AG with Async commit. I've gone through the below link but it is a mixture of 2 SQL Node in primary region with Sync Commit and 3rd SQL Node in Async Commit.

https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sql/virtual-machines-windows-portal-sql-availability-group-dr

Do we have any article for only Async commit in the DR Region/ Secondary Region?

Is this possible first of all and Will there be any LB in the primary Region? any guidance.
