You can use vSphere Fault Tolerance with vSphere Distributed Resource Scheduler (DRS).
FT VMs do not require EVC to support DRS. You can use FT with DRS on vSphere 6.5 and 6.0 hosts that are managed by a vSphere 6.7 or higher VC.
Note: vSphere DRS is a critical feature of vSphere which is required to maintain the health of the workloads running inside vSphere Cluster. Starting with vSphere 7.0 Update 1, DRS depends on the availability of vCLS VMs. See vSphere Cluster Services (vCLS) in vSphere Resource Management for more information.
