Micronaut: How can I use serialization inclucion ALWAYS with Micronaut Serialization?

Question

How is it possible to configure the Micronaut Serde objectMapper to include all properties when serializing, and not just the non-null values?

For Jackson the similar code looks like this:

new com.fasterxml.jackson.databind.ObjectMapper()
.setSerializationInclusion(JsonInclude.Include.ALWAYS)

Sample:

    @Test
    void testObjectMapper() throws IOException {
        var name = new Name("My first", null);
        var expected = """
                {"first":"My first", "last": null}
                """;
        var json = ObjectMapper.getDefault().writeValueAsString(name);
        assertEquals(expected, json);
    }

    @Introspected
    @Serdeable
    public record Name(String first, String last) {
    }

I want the json to be

{"first":"My first", "last": null}

and not just

{"first":"My first"}
