Pinging, which refers to preignition, usually doesn't happen at low power, low rpm scenarios, they are usually high power output events. I suppose it could happen at low rpm, engine lugging full throttle application, but that is generally not possible with an automatic transmission. Newer engines have knock sensors that when activated result in strategies, such as retarding the timing, adjusting mixture and other things to resolve the issue. I have not heard an engine ping in a long time. If your engine is pinging, the ecu should set a could that could be retrieved with a reader. There are no adjustments in modern cars, nor would it be wise to try to adjust things. Things that could go wrong should show some type of code set in the ecu.

I wonder if what you are hearing is something like a cv joint falling or maybe an exhaust component flexing?

Edit:

I just searched Youtube for: ford f 150 2018 5.0 pinging at low rpm , check out the results, may give you some ideas.
