infuse app on iPad with SSD?

I’ve been using the infuse app with an iXpand usb for a while now. Just upgraded my backup to a Sandisk SSD. Anyone try using an SSD with infuse? Or is this function truly supported only with iXpand drives?

Drive format will be the same in exFat. Figured I’d use Apple’s cable to make the link.

Tried emailing customer service with the question but didn’t hear back.

Thanks in advance

As far as I know regular hard drives are not supported by Apple regardless of what they are formatted as.
