Hi Charoenwan2512,
Interesting to see this generation of TB. This one was not available in the U.S. I would try and find a forum that is more oriented towards that body style. The two forums I know(trailvoy and GMNTNation) I don't believe they talk about this one.
This forum is more oriented towards the 2021 and newer body style. You might need to see if Brazil has a GM parts website that shows exploded parts diagrams, and then judge for yourself what part(s) you may need to make the change. Sometimes there are a lot more parts involved to make changes.
Good luck with your search.
