[JENKINS-45958] Excessive branch indexing

I'm using Blue Ocean and the declarative pipeline to describe a job. In the triggers section, I'm only using cron trigger. Nevertheless, Jenkins periodically reruns the job with the message "Branch indexing." The job takes a long time to complete and cleans resources at the beginning, making it very difficult to work with. If there is no pollSCM trigger set, then I don't believe this branch indexing should be occurring.
