There are several DOH severs.

You could also try:

curl -H 'accept: application/dns-json' 'https://dns.google.com/resolve?name=current.cvd.clamav.net&type=A'

... or even just:

curl 'https://dns.google.com/resolve?name=current.cvd.clamav.net&type=A'

You could query using DoH:
#curl -H 'accept: application/dns-json' 'https://cloudflare-dns.com/dns-query?name=current.cvd.clamav.net&type=TXT'
