How to combine 2 nginx rules?

Question

Nginx

How to combine these 2 rules?

location / {
        try_files $uri $uri/ /index.php?$args;

and authorization on certain URLs

location ~* (siteadmin|catalog) {
    auth_basic            "Restricted";
      auth_basic_user_file  /home/sitemarket/conf/web/.htpasswd;}

Authorization works, but CNC URLs stop working and gives a 404 error
. I can’t figure out how to combine all this so that both CNC and authorization on certain URLs work.
All configuration

    listen      ip:443;
    server_name site.kg www.site.kg;
    root        /home/sitemarket/web/site.kg/public_html;
    index       index.php index.html index.htm;
    access_log  /var/log/nginx/domains/site.kg.log combined;
    access_log  /var/log/nginx/domains/site.kg.bytes bytes;
    error_log   /var/log/nginx/domains/site.kg.error.log error;
if ($http_host = www.site.kg) {
  rewrite  (.*)  https://site.kg$1;

Add to the second rule
try_files $uri $uri/ /index.php?$args;
