Убрать слеш в конце ссылки. NGINX

При переходе site.ru/about кидает на site.ru/about/. Как убрать автоматическую подстановку слеш в конце ссылки в настройках NGINX, что бы было так site.ru/about Вот мой конфиг:

server {
        server_name sub.url.ru;
        root   /home/suburl/public_html/;
        index index.php;

        access_log /home/sportmen/sportmen.ru/logs/access.log;
        error_log /home/sportmen/sportmen.ru/logs/error.log;

        location ~ \.php$ {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_intercept_errors on; }
        if ($request_uri ~ ^(.*)/index.(html|php)) { return 301 $1/$is_args$args; }
        location / { try_files $uri $uri/ /bitrix/urlrewrite.php$is_args$args;  }
        location ~* @.*\.html$ { internal; }
        include /etc/nginx/vhosts-includes/suburl/redirect.conf;

        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/suburl/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/suburl/privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


###phpMyadmin###

        location /phpmy123 {
        alias /usr/share/phpmyadmin;
        location ~ \.php$ {
        fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        include fastcgi_params;
        fastcgi_ignore_client_abort off;
        }
        location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        access_log    off;
        log_not_found    off;
        expires 1M;
        }
}
        location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}
}
###end-phpMyAdmin###
server {

        if ($host = sub.url.ru) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80;
        server_name sub.url.ru;
        return 404; # managed by Certbot

Если я добавляю:

   if (!-f $request_filename) {
   rewrite ^/(.*)/$ /$1 permanent;
   }

То он начинает делать цикличное перенаправление на странице. Как убрать слеш в конце ссылок?
