display post in default language if translation is not available

Hi, is it possible to display page in default language if translation is not available without changing back to default language ?

If i have a page that have no translation and i will put it intentionally on menu of translated version of website, then if i click this page link, page opens in default language but also whole website changing back to default language and i don’t want that – i want to open page in default language ,but also stay at translated version of website.

I found this https://polylang.wordpress.com/documentation/documentation-for-developers/tips-and-tricks/how-to-display-the-default-language-post-if-the-translation-does-not-exists/ but it is outdated and also i think that this tutorial mention a slightly diffrent problem.
