SQL Always ON

Hi

SQL Version: SQL 2017 Ent edition

I have 4 VM's (VM1 Prod DB and VM2,VM3,VM4 replica of Prod that is HA/DR DB servers).

- VM1, VM2 are hosted on DC1 and VM3, VM4 are hosted on DC2.
- VM1 and VM2 are in windows fail-over cluster (A-A cluster): Cluster Name-> DC1_cluster
- VM3 and VM4 are in windows fail-over cluster (A-A cluster): Cluster Name-> DC2_cluster

Is it possible to configure SQL Always ON from VM1 to VM2, VM3 and VM4 DB servers? If it's not possible, what is the alternative solution for HA/DR?

I have two clusters. As per Windows team, it's not possible to add 4 VM's in same cluster because the VM's are hosted on different DC.
