Now that Zabbix is a part of the EPEL repo, you might need to exclude it from the DNF configuration, if your using the official Zabbix repository. The error will be something similar to the following:

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Edit the repository config: /etc/yum.repos.d/epel.repo, and add an exclude in the [epel] repository configuration:
[epel]
name=Extra Packages for Enterprise Linux $releasever - $basearch
# It is much more secure to use the metalink, but if you wish to use a local mirror
# place its address here.
#baseurl=https://download.example/pub/epel/$releasever/Everything/$basearch/
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-$releasever&arch=$basearch&infra=$infra&content=$contentdir
enabled=1
gpgcheck=1
countme=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-$releasever
### Blacklist nginx package ###
exclude=zabbix-*
run “dnf clean all” and “dnf update” again to check if the problem is solved.
Excluding Zabbix when Updating
Use the following command to exclude all Zabbix packages when updating;
dnf update -x zabbix-*
