spring-boot: Spring does not respect jpa bootstrap mode in application.properties

spring.data.jpa.repositories.bootstrap-mode has been reverted to default since spring boot 2.4.1. I want to enable spring.data.jpa.repositories.bootstrap-mode=deferred but it is ignored (logs says DEFAULT)

However it is correctly enabled if instead of setting an application.propety, I set it with @EnableJpaRepositories(“com.rebirthCorp.rebirth.repositories”, bootstrapMode = BootstrapMode.DEFERRED) Note: this might help you find the root cause of the bug: Multiple Spring Data modules found, entering strict repository configuration mode!

@SpringBootApplication
@EnableIntegration
@EnableJpaRepositories("com.rebirthCorp.rebirth.repositories", bootstrapMode = BootstrapMode.DEFERRED)
@EnableElasticsearchRepositories("com.rebirthCorp.rebirth.elasticrepositories")
class RebirthApplication
