Is the plural of CV: CV or CVs when the pluralised noun does not end in -s? [duplicate]

The answer to this question outlines a general rule for pluralising acronyms:

The general rule is that you should not use an apostrophe to form the plurals of nouns, abbreviations, or dates made up of numbers: just add -s (or -es, if the noun in question forms its plural with - es).

However, it is not clear from that answer what should be done if the noun in question uses does not end in either -s or -es.

What is the correct plural abbreviation for Curriculum Vitae?

I think the plural is Curriculum Vitarum (or possibly Curricula Vitae), which would make the plural abbreviation CV too. Use of the -s suffix suggests Curriculum Vitaes (or possibly Curriculums Vitae) which seems wrong.

What is correct?

Wikipedia uses "CVs", so I'd go with that
