Jenkinsfile conf

I have configured a Jenkins Multibranch Pipeline for a repository that contains three branches. I would like to specify which Jenkinsfile should be used by each branch, ensuring that each branch utilizes a unique Jenkinsfile. Is there a recommended approach for achieving this configuration?

Jenkins setup:
Jenkins: 2.484
OS: Linux - 4.18.0-553.22.1.el8_10.x86_64
Java: 17.0.12 - Oracle Corporation (Java HotSpotâ„¢ 64-Bit Server VM)
