After I posted I found the Mahmoud answer and I was able to implement it. Thank you!

BatchConfig.java

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class BatchConfig {

  @Bean
  public PlatformTransactionManager transactionManager() {
    return new ResourcelessTransactionManager();
  }

  @Bean
  public JobRepository jobRepository() {
    return new ResourcelessJobRepository();
  }

  @Bean
  public JobLauncher jobLauncher(JobRepository jobRepository) {
    TaskExecutorJobLauncher jobLauncher = new TaskExecutorJobLauncher();
    jobLauncher.setJobRepository(jobRepository);
    return jobLauncher;
  }
}

JobConfig.java

@Configuration
public class JobConfig {

  @Bean
  public Job taskletJob(JobRepository jobRepository, Step step) {
    return new JobBuilder("taskletJob", jobRepository)
      .start(step)
      .build();
  }

  @Bean
  public Step sampleStep(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
    return new StepBuilder("sampleStep", jobRepository)
      .tasklet(new SampleTasklet(), transactionManager)
      .build();
  }
}
