found the solution to apply css to each menu item with condition
Html.Kendo().Menu()
.Name("Menu")
.BindTo("web", (item, value) => {
if(item.Text.Equals("Home"))
{
item.Enabled = false;
item.HtmlAttributes.Add("style", "background-color:#CCCCCC;");
item.LinkHtmlAttributes.Add("style", "font-weight:bold; color:black;");
}
})
.Render();
