I would prefer to configure this by clearing the 'upstream' setting, which seems more intuitive for "there is no upstream" to me. But sadly, it seems that the CVO has been falling back to a default URI when the ClusterVersion upstream is empty since way back [1,2], and that this behavior is enshrined in the API [3]. Although the channel docs also talk about defaults [4], the only channel defaulting in the CVO is when creating a ClusterVersion object after the in-cluster copy was (accidentally?) deleted [5]. So maybe we could talk folks into adjusting the CVO logic to return NoUpstream in the empty-upstream case, but at the moment, clearing the channel is the best approach for "the CVO keeps complaining that it can't hit the upstream, and I want ot quiet it down [6]". The 'oc adm upgrade channel' command just landed for 4.9 in [7].
