301 redirect from http to https, how to make an exception?

Question

htaccess

Good afternoon!
Ordered and activated an SSL certificate on the server.
Specified a 301 redirect in the root directory in the .htaccess file.
RewriteEngine On
RewriteCond %{HTTP:PORT} !^443$
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI } [L,R=301]
All pages are now loaded via https
But! since the admin panel located at fcgl.ru/admin (not indexed by the Yandex robot) is set to http, now it does not work ...
My programmer will be able to do something not earlier than in a week. Can you please tell me how to set up a redirect exception for fcgl.ru/admin ?
