The language limitation of Japanese-only consoles

Hey guys I bought a ps5 slim with Japanese-only label. I am wondering, will the JB process and usage of backup from MW allows me to bypass the system language limitation or not? Cause some games can't change language inside and only follow the system languages. Any suggestions and experiences will be appreciated.

I have heard there are some language plug-ins which are just like backpork ones can be added to change the system language but here I hope we can discuss more :)
