If none of the existing interface types are suitable for your application, you have two options for creating a suitable interface.

The first option is to create an interface definition in the Vivado IDE by selecting Tools > Create Interface Definition. This is a useful approach if you need to use the interface in multiple decouplers.

The second option is to create an ad-hoc interface in the decoupler using the DFX Decoupler core customization page or configuration properties. To do this, create an interface of type undef and add signals that you require, as shown in the following figure.
