If you need do to this for testing purposes: since spring-test 5.2.5 you can use @DynamicPropertySource:

    @DynamicPropertySource
    static void setDynamicProperties(DynamicPropertyRegistry registry) {
        registry.add("some.property", () -> some.way().of(supplying).a(value) );
    }

Takes precedence over pretty much all of the other ways of supplying properties. The method must be static though.
