item.V_DriversVM is probably null, check it using if inline statement, and if there is no data, so display watever you want, else then display the name.
Try:
@foreach (var item in Model)
{
@Html.DisplayFor(modelItem => item.Desc)
@Html.DisplayFor(modelItem => item.Date)
@Html.DisplayFor(modelItem => item.StartTime)
@Html.DisplayFor(modelItem => item.EndTime)
@Html.DisplayFor(modelItem => item.V_DriversVM == null ? "No Data" : item.V_DriversVM.Name
}
