In https://github.com/theforeman/foreman_maintain/blob/master/definitions/reports/advisor_on_prem_remediations.rb#L14

the `advisor_on_prem_remediations_enabled` value is gathered via

@iop_enabled = feature(:installer)&.answers&.dig(
          'foreman::plugin::rh_cloud', 'enable_iop_advisor_engine'
        ) || false

In 6.18, this will always return false because the installer option has changed (I believe simply to 'iop'?)
