Using an Edge 130 plus (sw vers 2.50) with Garmin Connect, an activity report from a ride includes "Training Effect" for both Aerobic and Anaerobic, on a scale of 1-5. Not sure if that data is the same as what you are asking, though.
On a related note, it also generates a Recovery Time which is typically less than 50% that of what my Fenix 6 shows. For example, after a recent road bike ride my F6 showed a RT of 67 hours and the Edge 130 Plus showed 18 hours.
