Hi @frob ,

I'm afraid It's impossible if the list is in SharePoint modern experience. If it's a single attachment, you can use a SharePoint Document Library instead of a list, which each item is a document, which basically means it requires a document to start. This is why there is no OOB setting to set Attachments field to the required field. It is a best practise to clearly distinguish between list and library to make the most use of them in SharePoint Online.
