Agent should increase how long it allows the Endpoint installer/uninstaller to run to 10 minutes. Loading and unloading a kernel extension on macOS can randomly take a very long time. Endpoint cannot shorten this delay imposed by macOS.

We've found through experience that often under 30 seconds works and usually under 4 minutes works. We've never seen it take longer than 10 minutes to load or unload a kernel extension though, which is why we use that very long timeout.
