Possible to disable the camera sound in LG G5 (Korean version)?

[ywcc]

Hi there,
I bought this LG G5 in Korea (and now it's on Android 7 after the recent update), and wasn't aware of the fact we can't disable/mute the camera sound even if I put my phone on silent mode...
Is there any way to turn it off?
I read about rooting and changing the .ogg files. Is that the only solution for this problem?

Thanks in advance!
