Hello,
We don’t have such an option at this moment. You can enable it either on the single product or for all the products + all pages https://gyazo.com/1c83f46d2818362eeb46685b666afe3f
If you want to show “Request a quote” only on a specific page you can submit feature request here https://www.8theme.com/taskboard/
Or look for the third-party plugin that already has such option.
Regards
