Yes, all those procedures you mentioned are available in GDS.
"I'm not interested in update firmware, the dealer will have to do that for free anyway." - I think you are up to very big surprise here. Dealers are notorious for not performing any TSB updates whatsoever. It take 30 minutes to perform updates and they could not charge for it. So what they do? - they never bother to update, ever, unless you have a complaint or bring TSB to them and insist on it. I have Toyota, Honda (so called leaders among asian makers)- none received any updates, despite asking every visit to update my car. Sure, they will tells you "all looking good", you are "up to date", but nothing ever gets done. I just loaded to my 2009 Camry the AT rough gear shift update from 2009 in 2019 and yesterday loaded 2003 Accord with update from 2011 and it was way behind on any updates, despite countless air bag saga visits. Both updates were ongoing issues(not big, but annoying) on my cars, but I had no idea there is a fix for it.
So, if you want an update - you have to do it yourself or have a friend working at the steeler-ship to make it happen.
The only instance of ECU update proof - was Toyota after sudden acceleration re-call was performed on my car, as I did not do it for very long time, I finally brought my car to do it (5 or 10 years late) and sure enough they loaded ECU update for this specific recall, but they ignored AT update (it was just an extra mouse click). But all folks who went to do this recall earlier - only have pedal shaved and not the most critical ECU update that would override accelerator pedal input when breaks are engaged. ECU update released years later was the real fix, not shaving the pedal joke most folks got.
