Fastcgi cache inactive=30m

Hi all, as I see in the Nginx file fastcgi cache inactive=30m, the panel has a setting that allows you to set hours, days. I searched through the configuration files where it can be registered when I install 365d, but I didn’t see it. Is it actually installed for example 365d or does it follow the configuration of the Nginx file? Sorry, but I’m really interested)

fastcgi_cache_path              /var/cache/nginx/micro levels=1:2 keys_zone=microcache:10m inactive=30m max_size=1024m;
