If there's a way to deactivate a specific file on SS without actually deleting the file, what is it?

I thought there was, but when I change a file's categories both to "deleted" the file still gets downloaded, so that's not it.  Thank you.

Thanks so much for replying, but I should have been clearer that I was wondering how to deactivate specific file(s). Thought it had an option similar to DT's image-by-image deactivation, but I must have misunderstood. re exclusivity

If you go to https://submit.shutterstock.com/admin.mhtml, and opt out of everything underneath the "minimum payout" box, your images will no longer be available for sale.

Why? Thinking of going exclusive with iStock ?
