In 1.32.2 we did this: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/3c55db886a6062010450fd67645815e567b03bbf so that non-link-local non-deprecated IPv6 addresses are preferred for hostname lookup via DNS. However, I see in the trace log from https://bugzilla.redhat.com/show_bug.cgi?id=2050296#c5 that you are using NM 1.30 which doesn't have this commit. Would it be possible for you to try a more recent version of NM?
updating the RHCOS image directly as was done in the past is much more problematic with the presence of metal day-1 features. we've tried to update the NetworkManager post-deployment, however, since nodes are already bugged at this point, the node cant recovered from the necessary reboot.

Okay, this is probably a dupe of 1820770 then. I'm going to mark it that way since we still have the original bug to track the fix in the OCP product. Sorry for the noise, I mistakenly assumed we had that fix in our images already. *** This bug has been marked as a duplicate of bug 1820770 ***
