Change Doom Eternal language directly in the files

Tried the easy/normal way and it doesn't seem to work. Does anyone know an alternate way to change the language of the text and voices in the game?

Update: This isn't directly inside the files of Doom Eternal, but works like a charm: you can write "sys_lang en" on the console to change the language to English.
