Need help in nginx geoip2. How to convert if to map?

Question

Nginx

There was a question! How it is possible without using if but with map in nginx with the module --with_geoip2_module (dynamic) to block all countries except the chosen and all ip except the chosen, to make it work like this:

**if ($lan = yes ) {
set $allowed_country yes;
}

if ($allowed_country = no) {
return 503;
}**
but without if?

Centos 7

It`s my /etc/nginx/nginx.conf

load_module modules/ngx_http_geoip2_module.so;

user nginx;

worker_processes 1;

error_log /var/log/nginx/error.log warn;

pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

#block country

geoip2 /etc/nginx/geoip/GeoLite2-Country/GeoLite2-Country.mmdb {

auto_reload 60m;
$geoip2_data_country_code country iso_code;
$geoip2_data_country_name country names en;
}

geo $lan {
default no;
123.224.55.2 yes;

}

map $geoip2_data_country_code $allowed_country {

default no;
UA yes;
BG yes;
RO yes;
}

log_format geoip_main '$remote_addr - $geoip2_data_country_code - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent "$host" '
'"$http_referer" "$http_user_agent" "$gzip_ratio"';

access_log /var/log/nginx/access.log geoip_main;

access_log /var/log/nginx/geoip_country.log geoip_main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;

access_log /var/log/nginx/geoip_country.log geoip_main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;

#gzip on;

include /etc/nginx/conf.d/*.conf;
include include/etc/nginx/modules/*.so;

}
I am very grateful to you for your help!

geo $lan {
    default no;
    123.224.55.2 yes;
}

map "$lan,$geoip2_data_country_code" $allowed_country {

    default no;
    ~^yes  yes;
    ~,UA   yes;
    ~,BG   yes;
    ~,RO   yes;
}
