You can create a custom routing convention that selects the same controller no matter what the entity set is. Example,

public class CustomControllerRoutingConvention : IODataRoutingConvention
{
    public string SelectAction(ODataPath odataPath, HttpControllerContext controllerContext, ILookup actionMap)
    {
        return null;
    }

    public string SelectController(ODataPath odataPath, HttpRequestMessage request)
    {
        return "SomeFixedContrllerNameWithoutTheControllerSuffix";
    }
}

You can register that routing convention using the following code,

IList routingConventions = ODataRoutingConventions.CreateDefault();
routingConventions.Insert(0, new CustomControllerRoutingConvention());
config.Routes.MapODataRoute("OData", "odata", builder.GetEdmModel(), new DefaultODataPathHandler(), routingConventions);
