Jenkins multibranch pipeline Scan without execution

Question

Is it possible to Scan a Multibranch Pipeline to detect the branches with a Jenkinsfile, but without the pipeline execution?

My projects have different branc

Also, you can do it programatically

import jenkins.branch.*
import jenkins.model.Jenkins


for (f in Jenkins.instance.getAllItems(jenkins.branch.MultiBranchProject.class)) {
  if (f.parent instanceof jenkins.branch.OrganizationFolder) {
    continue;
  }
  for (s in f.sources) {
    def prop = new jenkins.branch.NoTriggerBranchProperty();
    def propList = [prop] as jenkins.branch.BranchProperty[];
    def strategy = new jenkins.branch.DefaultBranchPropertyStrategy(propList);
    s.setStrategy(strategy);
  }

  f.computation.run()
}

This is a Groovy snippet you can execute in Jenkins, it's gonna do the scanning but will not start new "builds" for all discovered branches.
