Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

You can however modify your product schema through our filters. Please refer to this guide here: https://rankmath.com/kb/filters-hooks-api-developer/#richsnippets
You may refer to this guide as well on how to apply the filter code on your website: https://rankmath.com/kb/wordpress-hooks-actions-filters/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
