99.99% of the time it's because of an incomplete Ecu calibration.
Aka how aggressive your "tune" is.
That in combination with sub par gasoline could absolutely create knock events such as what you're experiencing.
Remember. Creating a reliable and powerful "tune" for any car at WOT on a dyno takes about an hour or two.
Creating a reliable and powerful "tune" for partial throttle and partial load conditions take weeks/months of real world driving and logging.
I agree with most everyone's advice on here. Discontinue using your current "tune" and switch back to stock configuration. If you are still logging a knock event then there is a hardware issue. Even with poor quality gas.
If your knock goes away, then get a different "tune".
And no, you shouldn't ever experience any knock event whatsoever. If bumps/potholes are registering as knock events, then again, your "tune" is incomplete. Part of a full ECU calibration is setting knock sensor thresholds/sensitivity.
How do you think my BMW track car with 35 profile tires and all solid suspension mounting points would run if my Ecu was picking up "engine knock" every time I bumped a curb?
