Here [0] is the relevant documentation section.

host-managed=<boolean>
Whether this interface’s IP configuration should be managed by the host. When enabled, the host (rather than the container) is responsible for the interface’s IP configuration. The container should not run its own DHCP client or network manager on this interface. This is useful for containers that lack an internal network management stack, like many application containers.
