Service Broker - Content & Policies - Content - pick one blue print content and there are 3 little dots and a left side submenu for each content, click Customize Form - after Customization click Enable Custom forms is not a feature that have to be enabled on the Service Broker level. They are enabled on a per-catalog item basis so this answer makes the most sense.

Reference:
Once complete, the console shows the services and options which are available. You can add users and configure roles by selecting Identity & Access Management from the menu bar. If you're using Active Directory, remember you'll need to add those details in vIDM or LCM through Locker before users and groups will appear in vRA 8. In addition to the aforementioned services, vRealize Orchestrator (vRO) is accessible from the Console, as well as the vRA Migration Assessment. vRO no longer uses a java client. Instead you can access the embedded vRO via the new HTML 5 UI through this console. An external vRO appliance option is available too
