Thank you for reaching out!
Let me try and provide some insight into this matter; you are correct, Email Template will need to be enabled in this case for the email to be delivered. At this moment, there isn’t a standard template that gets sent without enabling ( and possibly customizing ) the particular one needed, in this case Verification Email ( code ). Testing this on my end yields the same result as you encountered.
To overcome the language issue, please look over this Knowledge Article that provides a workaround to adapt the email templates according to the user’s language.
