Spring Dynamically change the application properties defined in the YAML file while running Springboot tests

My Use case is,

organisation wide all our microservies are using YAML, so we cannot move from YAMLto .properties. In one of my recent app, I am using testcontainers for Unit tests, where testcontainers randomly selects any available port to start the container. So before running the tests I have to dynamically change the PORT property which is defined in the YAML file. For .properties file, it was straightforward with ApplicationContextInitializer& TestPropertyValues- like TestPropertyValues.of("spring.rabbitmq.port" + container.getMappedPort(5672)).applyTo(applicationContext);

Not able to achieve this, being the port property is defined in the YAML file.

Any workaround / suggestions ?

Which version of Spring has this annotation. Currently our enterprise is on SpringBoot 2.2.4.RELEASE version.
