Honor 7 - native call recording?

I found, that in Chinese firmware (PLK-UL00C17B162) there is an option to record phone calls.
Unfortunately, I don't have this option in my firmware - PLK-L01C432B100 ( (Poland).



Is there any chance to turn on this unavailable option in PLK-L01?
Or only way is change the firmware - to this Chinese? (Is this required unlocked bootloader?)
