To remove the word 'from' for your product overview page, this can be done from your theme's language settings. To access the language settings go to Online Store > Themes > Narrative > Actions > Languages. In the search bar of the language settings, type 'from', then scroll down to remove the word 'from' in the from txt html section and press save.
This will remove the 'from' text when you have ranging prices of variants, and just show the lowest price of the variant.
Hope this helps! If you have any questions on this please feel free to reply.
