How to set preferred route for NavMeshAgent?

Question

Unity

Good afternoon! The fact is that I have several agents in the scene. They go to different places. But when one agent goes somewhere, it is necessary that he bypasses, albeit with a long route, but not through another agent, not next to him.

I can't mark these zones as notWalkable, because agents should be able to walk there.

2D game, I use NavMeshPlus-master.

I would appreciate any help, thanks
