Set updater DNS server

[lordlightman]

Hello. Does anyone know if there is a way to change a DNS server for server update configuration?

I'm running my own DNS server and I want all requests from Gluetun to pass through it. I've set DNS_ADDRESS environment variable to achieve this but the updater uses Cloudflare nonetheless.
