How to configure nginx to not have a trailing slash?

Question

Nginx

hello, tell me please, I can’t figure out the nginx config, I seem to have made a redirect with a trailing slash, but all search engines consider the site a duplicate. https://photo-gileva-olga.ru/ and not https://photo-gileva-olga.ru, when I copy the url from the browser, it also adds a slash at the end

server {
    server_name www.photo-gileva-olga.ru photo-gileva-olga.ru;
    return 301 https://photo-gileva-olga.ru$request_uri;
}

server {
    listen 443 ssl;
    server_name www.photo-gileva-olga.ru;
    ssl_certificate /etc/nginx/ssl/photo-gileva-olga.ru.crt;
    ssl_certificate_key  /etc/nginx/ssl/photo-gileva-olga.ru.key;
    return 301 https://photo-gileva-olga.ru$request_uri;
}

server {
    listen 80;
    listen 443 ssl;
    server_name photo-gileva-olga.ru;
    root /var/www/photo-gileva-olga/public;

    ssl_certificate /etc/nginx/ssl/photo-gileva-olga.ru.crt;

             return 301 $1;
    }

    if ($request_uri ~ ^(?P<left>[^?]*?)//+(?P<right>[^?]*)) {

slash in https://example.com/ or any other site - the root path in the URL, it cannot be removed.
