The recover dialog you are showing appears during the launch of InDesign when any document(s) hasn't been properly saved—maybe you've lost a connection to the file's server and had to force quit in order to get ID working?
Setting the user interaction to never won't work because ID has to be launched before you can set the interaction via scripting.
If you were able to find a way to disable the dialog you would then no longer be able to recover work lost during a crash—so you better not forget to save.
If you simple click Cancel the dialog won't appear on the next launch.
