The nmstate operator provides what we need to do the blocking using cluster wide configuration.
https://nmstate.io/kubernetes-nmstate/user-guide/102-configuration

The general approach with nmstate:

inspect the cluster to block, collect all addresses
prepare NetworkConfigurationPolicy specifying the blackhole routes
apply the policy to the target clusters
wait until the policy is applied

Status

Seems that blackhole route is not support yet:
