Hi Lou - There is not way for a customer to bypass the requirement for DH8 or SV1 for TCT. However, I did check and we have a demo facility where we can do a remote Storage Hands On Workshop (SHOW) that you could see how to set up and use TCT. I know this is not as good as having a test environment in your shop but it is better than nothing if you don't have the correct nodes in your test environment. You should be able to reach out to your storage CTS to set up the SHOW. Feel free to email me if you want to discuss.
