Localization for custom fields options

Can we translate the customFields / variations options that are shown in the cart ? For example if i have a custom field for the Size, i want to display “Grandeur” in french in the cart, and “Petit, Moyen, Grand” instead of “Small, Medium, Large” in the cart dropdown. But i still want it to be binded to the correct variation for stock inventory ?

I’ve had a confirmation that this was not possible.
