Hi @shypervisor ,
You should be able to connect Trident to ONTAP simulator. Here is instructions on configuring ONTAP and connecting it to trident.
Link: ONTAP Configuration for Trident
There is also additional information in that link on how to fully configure Trident. Also want to mention that you can go to the NetApp Trident github for additional assistance.
Let us know if you have any additional questions.
Thanks
Team NetApp
