Hey,
If you are trying to build Failover Cluster without AD, you will need to create consistent local account on every node in the cluster. In addition, every node in the cluster should have primary DNS suffix. Check for more information: https://techcommunity.microsoft.com/t5/failover-clustering/workgroup-and-multi-domain-clusters-in-windows-server-2016/ba-p/372059
In addition, the following guide should help with configuration: https://www.starwindsoftware.com/resource-library/starwind-virtual-san-for-hyper-v-2-node-hyperconverged-scenario-with-windows-server-2016/
