Force HTTPS on .htaccess but only on production

I want the snippet above to work only when I use it on production, e.g example.com)

You can restrict your rule to only target example.com using a rewrite condition:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,NE,R=301]
