Is there any documented procedure to safely downgrade from rawhide

I tried
# dnf update --releasever=32 fedora-release

Does something like that have any chance of working? At first sight, it
seems to be somewhat successful.
I have downgraded at least a subset of packages from Rawhide to a
released Fedora in the past, and it can work.
However last week when I did this libvirt broke all networking when
doing this (requiring a reboot and IIRC some manual config file
changes to recover). Now this wasn't necessarily libvirt's fault
because we only test and it's only guaranteed that things like RPM
scriptlets will work in the forwards direction. While it's _nice_
that they should work in the reverse direction, it's not required and
it's very rarely tested.
So basically it may work, if it doesn't you get to keep all the pieces,
and it has broken in the past.
