Steps to reproduce:

1. Install zabbix 4.4 repo on centos 7 

rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

1. [zabbix-non-supported]by default is enabled.

[root@nagios04 yum.repos.d]# more zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=http://repo.zabbix.com/zabbix/4.4/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=http://repo.zabbix.com/zabbix/4.4/rhel/7/$basearch/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1
[root@nagios04 yum.repos.d]#

1. I had to disabled [zabbix-non-supported](turn enabled=0) so that following command will install zabbix-agent-4.4.5

yum --disablerepo=epel install -y zabbix-agent 

1. ...

Result:

[root@nagios04 yum.repos.d]# rpm -qa |grep zabbix
zabbix-agent-4.4.5-2.el7.x86_64
zabbix-release-4.4-1.el7.noarch
[root@nagios04 yum.repos.d]#

Expected:
Without manual disable of  [zabbix-non-supported], the latest zabbix-agent-4.4.5 should be installed , not the zabbix-agent-4.0 version
