Hi… Try deploying from the command line with fly launch; it looks like it will allow you to opt-out of creating a Tigris bucket, etc.:

In general, the Web UI for launching is still considered experimental (last I heard), and it doesn’t have the full set of knobs, feedback mechanisms, …
Hope this helps a little!
