As ColinTaylor indicated, the subject of the Ai Protection and TrendMicro feature on Asus routers has been discussed
very extensively in numerous past discussions that can be found using the subforum search feature. You should read the EULA and notices for both, including following the links to additional documents, and decide for yourself if
YOU are comfortable with the information that gets sent to Asus and TrendMicro when those features are active/enabled. Many have their own opinions. Some use the features, some don't.
An example of the EULA and notices one see's when they hit the router QiS page was
posted here (it may have changed since that posting).
PS: Many years ago (2020) RMerlin, the Asus-Merlin developer, made a post to address the questions many people had on the Trend Micro data collection in the 384.6 firmware:
