You could use an extension method like so:

public static bool IsValidExclude(this ModelStateDictionary modelState, params string[] exclude)
{
    foreach (var key in exclude)
    {
        if (modelState.ContainsKey(key))
            modelState.Remove(key);
    }

    return modelState.All(m => m.Value.Errors.Count == 0);
}

Then just call:

var result = ModelState.IsValidExclude("Password");
