Yes. By setting ProfilerRecorders up that record the relevant Render Thread Base samples, like Camera.Render.

Keep in mind that some of these occur on the main thread and the Render Thread. So to isolate out the Render Thread times for those, set up 2 recorders each. One set to record from all threads, one to only record the current thread (i.e. main thread). Then subtract the main thread times from the Render thread ones. Be mindful when in the frame you measure this as the render thread might still be busy with some of those markers that started in the previous frame.
