Fail2ban installed by default ? How to disable ?

Hi, sorry to ask, but how do I remove fail2ban from my CentOSv7.5 with Virtualmin
I tried yum remove fail2ban, but yum can’t find it in both repos, any help much appreciated.

yum remove fail2ban Loaded plugins: fastestmirror No Match for argument: fail2ban No Packages marked for removal

yum --enablerepo=epel remove fail2ban
Loaded plugins: fastestmirror
No Match for argument: fail2ban
No Packages marked for removal


I want to use CSF only.
