Does Jenkins 2.289.2 have a customizable workspace?

Question

I don't know where this is set, but jobs from my Jenkins 2.289.2 server appear to be working out of the directory /home/jenkins/workspace/${job_name}. E.g. if I have a minimal pipeline script that just touches a path-unspecified file, it ends up in that directory.

Question: where is this setting viewable or editable in the Jenkins web UI?
Question: (assuming this is an editable setting) is this editable per-job, or is this only a global configuration?
Question: is this setting viewable in "Configuration as Code"? I don't see the directory anywhere in the yml generated by the View Configuration button at ${jenkins_url}:8080/configuration-as-code/

Your first question is a duplicate of this question.

Your second question. Each machine has a setting. So the Jenkins controller and the Jenkins Agent/s will each have its own setting.

You can change the workspace inside a pipeline. But I have never seen anyone do it.

I can't answer your last question because I don't have a jenkins with that plugin to look at but it is something that can be configured. I see in the README an example for setting it on an Agent.

EDIT: Thanks to @Ian we now know that those setters were moves to system properties. With that information I was able to research more on JasC and found that you can set the rawBuildsDir if you use the restricted flag. But you can set the workspacedDir unless you drop into a groovy init file. You can find all the information in this GitHub issue.
