When running a try push (recommended by @jmaher) in this format ./mach try fuzzy --all-tasks --preset os_integration -xq 'windows10-64' --worker-suffix win10-64-2009=-alpha --worker-suffix win10-64-2009-gpu=-alpha --worker-suffix win10-64-2009-source=-alpha --push-to-vcs here is the treeherder results.
