KB5028623 is the June 23, 2023 (OS Build 14393.5996) Out-of-band. KB5030213 is the September 12, 2023 (OS Build 14393.6252) cumulative update that includes the KB5028623 updates so it isn't possible to install the older update, it also is not needed because all of the previous monthly roll-ups and OOB are included.
