C# Mongo BsonSerializer.Deserialize Ignore elements that do not exist

Is there a flat that will tell the C# Mongo BsonSerializer to ignore elements that do not exist in the poco class

Example collection

Animal {"Type" : "Cat", "Skill" : "Jump"}
Animal {"Type" : "Dog", "Skill" : "Bark", "Owner" : "Jimmy"}

If the cat C# class only has

public string Type {get;set;}
public string Skill {get;set;}

When I attempt to execute the following 

 var test = BsonSerializer.Deserialize<Animal>(result);

The first item will work fine, the second one will throw an exception that Owner does not exist.

Or you can use Convention to do it for all types at once

var conventionPack = new ConventionPack { new IgnoreExtraElementsConvention(true) };
ConventionRegistry.Register("IgnoreExtraElements", conventionPack, _ => true);

Use [BsonIgnoreExtraElements] attribute on Cat class.
From attribute summary:

Specifies whether extra elements should be ignored when this class is deserialized.

Maybe you can deserialize as an object, and use dynamic to receive it.

dynamic test = BsonSerializer.Deserialize<object>(result);
