It is possible to have an environment with an external engine (physical one
or as a virtual machine in an external env) and then use a host as the only
hypervisor

If the storage component has to be provided by that host itself you have to
use local storage based datacenter and storage domains as well:
https://www.ovirt.org/documentation/administration_guide/index.html#sect-Preparing_and_Adding_Local_Storage
If you want to retain the default datacenter created during installation,
you have to edit it and set it as "Local" in "Storage Type" section.
Or you could create  a new DC with that setting

There is also the option to install with Self Hosted Engine and use shared
storage (NFS, SAN, iSCSI,...) if you have one available:
https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_command_line/index.html#Installing_the_self-hosted_engine_deployment_host_SHE_cli_deploy
Or with the same guide use the host storage itself, but as GlusterFS and
eventually extend it later if/when available with other hosts
Of course in that case you loose all the HA functions available at host
level
