##### SUMMARY
<!--- Describe the new feature/improvement briefly below -->
dnf has a nobest [option](https://dnf.readthedocs.io/en/latest/command_ref.html#options-label) which does the following:

> --nobest
>     Set best option to False, so that transactions are not limited to best candidates only.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
dnf

##### ADDITIONAL INFORMATION
<!--- Describe how the feature would be used, why it is needed and what it would solve -->
Docker cannot be installed on CentOS8 without `--nobest` option and later on every time you want to do dnf upgrade you should pass `--nobest` option again, so that it does not complain about `docker-ce` package.
