Is there a way to batch Export mulitple INDD files to IDML across a drive?

...or a Mac script? Rather than open up every file and Export as........? Affinity 3 is out and free.

Have a look at the Batch Exporter script:

If your point is that you want to batch-convert to IDML in order to move to Affinity:

Just keep in mind that you won't be able to seek scripts or other automation solutions for Affinity as it's not currently scriptable or otherwise extendable. (Photo and Designer do have some minimal automation options which still don't come even close to what Adobe offers, while Publisher has none).

Thank you to all for responses. Duly noted.
