Default [Q] Modify the LG SmartWorld app in English for Korean G Flexes?

Hi, is it possible to modify the LG SmartWorld app to English in order to use it for font and theme changes for Korean variants?
I found some versions of the app in .apk form, but right after installation the app asks for an update. The update is ofc. for the Korean language and variants. Any workaround to bypass the model check or whatever?
