Front Page Sections by Theme

I’m trying to use a Onepage Theme which allows to add multiple sections to the Front Page – AFAIK also saved as own fields in the database. It seems this is not compatible with the Polylang concept to create a “static page” for every language while the Theme allows only one page to be selected as Front Page and therefore only the sections/fields for one (the primary) language can be edited with the Theme Customizing.

Using Gutenberg Blocks or Elementor etc. is not really an option as this onepage theme (the frontpage sections) is highly customized in a child theme for the brand and it it should be avoided to recreate the styles trough additional development.

I would like to ask if there is any possibility to work around this to create a customized front landing page for every language?
