Yes, you're right, TLS 1.3 dropped fixed-dh support, but we've a while back
dropped support for all the (authenticated) corresponding TLS 1.2 ciphers!
$ OpenSSL_master/bin/openssl ciphers -stdname -v ALL | grep _DH_ | awk
'{print $1}'
TLS_DH_anon_WITH_AES_256_GCM_SHA384
TLS_DH_anon_WITH_AES_128_GCM_SHA256
TLS_DH_anon_WITH_AES_256_CBC_SHA256
TLS_DH_anon_WITH_CAMELLIA_256_CBC_SHA256
TLS_DH_anon_WITH_AES_128_CBC_SHA256
TLS_DH_anon_WITH_CAMELLIA_128_CBC_SHA256
TLS_DH_anon_WITH_AES_256_CBC_SHA
TLS_DH_anon_WITH_CAMELLIA_256_CBC_SHA
TLS_DH_anon_WITH_AES_128_CBC_SHA
TLS_DH_anon_WITH_SEED_CBC_SHA
TLS_DH_anon_WITH_CAMELLIA_128_CBC_SHA
We should perhaps also drop the fixed DH anon ones too, leaving them in might
have been inadvertent.
