How can we avoid the parameter @p__linq__0 in EF Generated SQL?

Question

This SQL was generated when you pass a parameter from a variable

SELECT 
    ..
    FROM ( SELECT TOP (1) 
        ..
        FROM   (SELECT ..
            FROM  [dbo].[PurchaseOrders] AS [Extent1]
            INNER JOIN [dbo].[Parameters] AS [Extent2] ON [Extent1].[StatusId] = [Extent2].[Id]
            WHERE [Extent1].[Deleted] <> 1 ) AS [Filter1]
        INNER JOIN [dbo].[Suppliers] AS [Extent3] ON [Filter1].[SupplierId] = [Extent3].[Id]
        WHERE ([Filter1].[Id1] = @p__linq__0) AND ([Filter1].[LocationId] = @p__linq__1)
    )  AS [Limit1]

While if you pass a constant the generated SQL is much simpler

SELECT 
    ..
    FROM ( SELECT TOP (1) 
        ..
        FROM   [dbo].[PurchaseOrders] AS [Extent1]
        INNER JOIN [dbo].[Parameters] AS [Extent2] ON [Extent1].[StatusId] = [Extent2].[Id]
        INNER JOIN [dbo].[Suppliers] AS [Extent3] ON [Extent1].[SupplierId] = [Extent3].[Id]
        WHERE ([Extent1].[Deleted] <> 1) AND (2 = [Extent1].[LocationId]) AND ([Extent1].[Id] = @p__linq__0)
    )  AS [Limit1]

so, how can we tell EF to generate 2nd SQL without using constant?
