How to remove IP from network adapter?

Trying out beta, have system with 2 nics (+ipmi), I want to use second nic for docker and vm only, I am trying to remove IP from nic config, on test settings web ui reconnects, and I am back at the nic with IP.
How do I remove all IP’s from a nic so I can use it for docker and vm’s (in proxmox debian I normally need to first create a bridge?)
