you can:

rpm -e --justdb centos-stream-release

dnf update redhat-release -y

rpm -i --justdb --nodeps --force "http://mirror.centos.org/centos/8-stream/BaseOS/$(rpm --eval '%_arch')/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm"

Alma, Rocky and others are providing centos-release in their own release rpm so this step is not needed there.
