Is there really no other source of Holmium Ore than the 1% chance in scrap and the deconstructables on Fulgora?

No. No other way.

You can however put Productivity modules into the entire holmium chain if you feel like you are not getting enough out of the scrap. ^^

Also, Holmium Plate can be made in an assembling machine, but if you make it in a foundry you get an additional 50% productivity.

Yes there is, but it is not automatic

Depending on what quality you've got to work with, it's possible to make recycler loops that recycle everything and filter out just what you need, be that holmium, stone, batteries, whatever. You can basically turn any given scrap pile into a source of just some subset of the resources.
