Replace text on specific pages

Hi there!

I am trying to replace one string on certain product pages on my website. For example: https://associationgrainesdespoir.org/boutique/small-clutch-bag.
I would just need to change “poids” to “weight”

Some product pages are in French and should not be modified.

Is this possible using Say What?

Thank you!

Best regards,

Pauline
