How to disable https for specific URLs?

Question

Nginx

It is necessary to disable https for url of the following types:
/mailview?.....
/msd?....
/separator?....
To make them work over http. Now there is no general gluing, it works over http and https, you need to enable https for the entire site except for 3 urls:
listen xxx.xxx.xxx.xx:443 ssl http2;
If without Strict-Transport-Security, do this:

if ($scheme = http) {
rewrite ^ https://$http_host$request_uri? permanent;
}

Is it possible somehow to slip these 3 URLs here so that this rule does not work?
I googled for an hour on the Internet, there is nothing like it anywhere, neither on stackoverflows, etc., etc.
