Only trigger Jenkinsfile build for changes to certain paths

I have a Jenkinsfile for several multibranch pipelines in the same repository, and one thing I find frustrating is that all pipelines are triggered when I make any change, when often in reality only one pipeline actually needs to be triggered.

Is it possible, using a Jenkins file, to selectively include or exclude paths that will result in a build being triggered?

I'm thinking of something similar to below, but looking at the documentation I cannot see any reference to such a simple way of doing this. However, I'm new to Jenkins so I'm hoping that I'm missing something.

pipeline {
    agent {
        label 'Codebuild'
    }
    trigger {
        include '/some/path
    }
    stages {
        stage('Do the magic') {
            steps {
                script {
                    ...do stuff here...
                }
            }
        }       
    }
}

You can use the when conditionto determine whether the stage should be executed depending on the given condition.
In this can you can use the option/condition changeset to limit stage execution only to the case when specific files are changed.

For more info about when and changeset option :
https://www.jenkins.io/doc/book/pipeline/syntax/#when

Example:

stages {
    stage('Do the magic') {
       // Below condition you can change based on your usecase
        when { changeset "src/*.js"}
        steps {
            sh "make build"
            ...

        }
    }
