You will have to use the ConfigureStorageDrsForPod_Task method to change the settings for SDRS.
In the StorageDrsConfigSpec object you can disable this.
Combined with your Where-clause this could be something like this
$storMgr=Get-ViewStorageResourceManager
$pod=Get-DatastoreCluster-Name$datastorecluster
$spec=New-ObjectVMware.Vim.StorageDrsConfigSpec$pod.ExtensionData.PodStorageDrsEntry.StorageDrsConfig.VmConfig|where {(Get-View$_.VM|Select-ExpandPropertyName) -like"*_replica"} |%{ $entry=New-ObjectVMware.Vim.StorageDrsVmConfigSpec
$entry.Operation="edit"
$entry.Info=$_
$entry.Info.Enabled=$false
$spec.vmConfigSpec+=$entry
}$storMgr.ConfigureStorageDrsForPod($pod.ExtensionData.MoRef,$spec,$true)
Note that the Get-DatastoreCluster cmdlet can be used to replace my function
