How can I guarantee that there is only one if some Jenkins assignment is completed?

Question

I have several integration tests in my Jenkins work. They run on multiple application servers, and I want to make sure that one application server at a time is performed only test task one's .

I need something like a tag or variable in my tasks, which create a group of tasks and then set up the logic inside this group, only one task can work at a time.

Can I use an exception module for this? Does anyone have any experience?
