Still possible if you configure A VM without NIC. However, the kvm built-in nat solution is not optimal and therefore not offered any more in GUI. We recommend to configure NAT via iptables in Proxmox host, see example in https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_network_configuration (chapter 3.3.5).
