Disabling a certificate on a specific site page?

Question

htaccess

Hello, after switching from http to https, the iframe stopped working, so they use an http connection there.
Apparently, until there is https , it will not work if I have Https enabled.
The htacces file has a redirect to https.

RewriteCond %{SERVER_PORT} !^443$
 RewriteRule ^(.*)$ https://site.com/$1 [R=301,L]

As I understand it, the only crutch not to remove the certificate is to remove the https connection on this one page.
How good is the solution?
Tell me how to fix the htacces file in this case, so that it is on this page that it redirects back to http.
As I understand it, there are no other options ... or rollback from the entire https site.

RewriteCond %{REQUEST_URI} !ваша_страница
