iPhone 8 shutter sound not turning off.

I have an iPhone 8 and whenever I go to take a picture my phone always makes the shutter sound, regardless to either if my ringer is off or my sound is all the way down. I have done some research and I am seeing it is a possibility that my iPhone was from Japan or Korea where they purposely make the iPhones like this. If this is my case, is there anything I can do to turn off my shutter!!
