Automatic Transmission Oil Change for Hyundai i40 2014 at 172000km - Guidance Needed

Hello.
Can I change the oil in the automatic transmission (static or dynamic)?
Mileage 172000 km, 2014
Mostly highway, max. Two passengers.
In the instructions is that you can every 90000km, but the authorized service advises against.

Please replace statically. You won't change the oil filter, it is built into the chest.

Because he cannot or does not cut off the branch on which he sits. The chest will fall, it will be a profit.
You only need to follow the recommended oil and quantity very carefully. Another might spoil it quickly

Only dynamically. Static replacement is fiction and asking for trouble in the future, especially in crates where oil has never been changed and with high mileage.

Static exchange is certainly safer. You need equipment and skills for dynamic use. A small delay in topping up and you can break the crate. Probably why not everyone undertakes it. A medium-skilled amateur will make a static exchange even at home under the block.

As for fiction, I will disagree. I know a few mechanics who are behind this exchange method, but they advise against dynamic exchange. I exchange static in a car already 3 and (knock) everything works. If someone has a crate, any exchange would not help.
