TSB 23-008 Product Update: PGM-FI Idle Stop Software Update (2016-2022)

Is this for all vehicles in that age range or limited to certain VIN? As @hokiefyd mentioned, this recall is not showing up either on NHTSA or honda owner site. The dealer I purchased the vehicle from did send me an email for this recall. I have a '19 EX-L AWD and my vehicle doesn't have the start-stop system.
