Twig Translation String without Enabling Interface Translation

Is it possible to provide translation strings to Twig, without the Interface Translation module enabled?

We have Content Translation enabled but do not want to enable Interface translation (we would like the Drupal administration menu system to remain in English).

We have a couple of landing pages that base most of their content on a translated entity however, there are still a few labels and links we would like to translate using {{ ‘foo’|t }} in Twig.

Is this possible? And if so – where would the translation stings be stored?
