Question about Region setting in Redmi note11

Yesterday I wanted to change the language in my Redmi Note11, but by accident, I saw Region setting set as United States(system). I want to ask that, I live in Thailand, bought this phone in Thailand and never been to USA. If I leave this “region” setting as USA instead of Thailand, Does it affect to 1. My Security and Privacy 2. My mobile data charge and cost 3. My Wi-Fi Security and Privacy 4. My phone feature
