Comment 9 for bug 2029857

> Im as confused as Felipe. If you set enable_amphora=False, disable_ovn=True then you should get
"enabled_provider_drivers = amphora:The Octavia Amphora driver", per Alan's comments on #4. The user experience is terrible but, I think you still can achieve what you want.

@sombrafam where is the 'disable_ovn' option? it doesn't appear in the built charm. Also, there's no enable_amphora option, it's "enable-amphora".

The current master branch template for octavia does this from xena (which is the latest template version):

[api_settings]
{% if options.enable_amphora -%}
enabled_provider_drivers = amphora:The Octavia Amphora driver,ovn:Octavia OVN driver
{% else -%}
enabled_provider_drivers = ovn:Octavia OVN driver
{% endif -%}

i.e. there is no way to switch OFF the ovn driver at the moment. This bug is about switching off the ovn driver completely as if it fails the octavia API exe fails.
