dnf history undo last - Cannot find rpm nevra

I have done an update on AlmaLinux 8.6 to AlmaLinux 8.7. I would like to undo the update but it is not letting me. Here's the error message: Error: The following problems occurred while running a transaction: Cannot find rpm nevra "NetworkManager-1:1.36.0-9.el8_6.x86_64". Cannot find rpm nevra "NetworkManager-adsl-1:1.36.0-9.el8_6.x86_64". Cannot find rpm nevra "NetworkManager-bluetooth-1:1.36.0-9.el8_6.x86_64". A simple way of undo would really be nice. Is there a way of backup a state of machine in order to revert easily should something go wrong?
