Fortunately, fanout is one of the first things it does. You should be able to find a combination of track width, via OD, and grid that will cause the vias to be placed far enough apart to allow a trace to pass between them. It may take some tinkering. You may want to set particular rules, just do fanout in the autorouter run, then change the rules and run again, with lock all preroutes.
