Can laravel be configured to an existing site path in nginx?

server{
        listen 80;
        server_name sms.dev;
        index index.php index.html index.htm;
        root /var/www/html/sms;
        location /laravel/ {
            # 这里如何配置呢?
        }
        location ~ .*\.(php|php5)?$
        {
                fastcgi_pass  127.0.0.1:9000;
                fastcgi_index index.php;
                include fcgi.conf;
        }
        
        if (!-e $request_filename) {
                return 404;
        }
}

location ^~ /app/ {
    alias /var/www/laravel/public/;
    if (!-e $request_filename) { rewrite ^ /app/index.php last; }
    location ~ \.php$ {
        if (!-f $request_filename) { return 404; }
        include snippets/fastcgi-php.conf;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }
}
