Disable camera shutter sound

I'm using the iPhone 12 Japanese region version in Sri Lanka. I know that the shutter sound on the iphone is a must to Japan consumers but since I'm using the phone outside Japan as many others in my country where they sell the Japanese version by the Apple authorized dealers it's unfair to have the shutter sound on by default and not being able to mute it.

Are there any way to mute the sound for users outside Japan?

As a matter of fact when capturing images in a class room with about 100 students the phone makes a shutter sound and it's kinda embarrassing to use it further.. same thing happens at the movies..
