Not as far as I can see.
public static void Foo<T>(IEnumerable<T> value) => Console.WriteLine($"Foo<{typeof(T)}>(IEnumerable<{typeof(T)}>)";
public static void Foo<T>(params T[] value) => Console.WriteLine($"Foo<{typeof(T)}>(params {typeof(T)}[])";

public static void Bar()
{
    Foo(42); // Foo<int>(params) - Correct
    Foo(Enumerable.Range(1, 42)); // Foo<int>(IEnumerable) - Correct
    Foo(new[] { 1, 2, 3 }); // Foo<int>(params) - Correct
    Foo(new List<int> { 1, 2, 3 }); // Foo<List<int>>(params) - *** INCORRECT ***
}
Generic Overload Resolution 2 | C# Online Compiler | .NET Fiddle[^]

If you pass a List<> to the method, it calls the params overload passing the entire list as the first parameter. The type parameter will be List<>, not the type of the list's elements.
