What’s the proper way to downgrade a package using download RPM on ostree variants?

I’m currently on F37 Kinoite, a firmware bug in linux-firmware-20230404-149 is forcing me to downgrade to linux-firmware-20230210-147.fc37 But I’m having trouble doing that. When I try the usual
rpm-ostree override replace "https://koji.fedoraproject.org/koji/buildinfo?buildID=2149541" I get errors downloading a subpackage for iwl firmware so the command fails (I don’t even need that firmware package). I tried a few times to make sure it’s not transient, but no dice, that url is gone for good.

I then tried to download the rpm and install manually with
rpm-ostree install ./linux-firmware-20230210-147.fc37.noarch.rpm but it errored again:

error: Could not depsolve transaction; 1 problem detected:
 Problem: cannot install both linux-firmware-20230210-147.fc37.noarch and linux-firmware-20230404-149.fc37.noarch
  - conflicting requests

So let’s try removing the installed package:

rpm-ostree override remove linux-firmware
Removed:
  linux-firmware-20230404-149.fc37.noarch
Use "rpm-ostree override reset" to undo overrides

Rebooted, try installing again:

rpm-ostree install ./linux-firmware-20230210-147.fc37.noarch.rpm
error: Base packages not marked to be removed: linux-firmware

I don’t understand this error message, and at this point I don’t know what to try anymore. What’s the proper way to downgrade a package using download RPM on ostree variants?

Have you tried:

rpm-ostree override replace ./linux-firmware-20230210-147.fc37.noarch.rpm

?
