How to enable SSL only on Stripe payment page?

Hi,

How to enable SSL(HTTPS) only on Stripe payment page during checkout but not on whole network or front end of the multi sites? We have SSL certificate installed on our NGINX server but as soon as we activate it, SSL get applied to all sub domains, mapped domains and our main website also thus breaking several things. However we just want to enable this SSL for Stripe Payment purposes only.

Kindly suggest the configuration. We are using Domain Mapping, Pro-Sites plugin.
