Webstudio does it all now. I went though this a couple months ago.
No BIS-F needed for this, if you do it this way. I still made sure I didnt sync my golden image though, and just kept the leave switch on it for a cya. Synced the VDA OU with Entra AD connect. It will go through the process and do it for you during the catalog creation. But the VDA won't register until the Entra ID object is up in Azure then it will register to the CC/DCC.
It gives some details in the catalog as well
