Make sure the “Automatically manage…” is nit selected and you should be able to set the paging file for each drive separately. System managed for the main OS drive (usually C:) and any other SSDs you run apps from is fine. Old hardrives and other drives that are just for storage should have “None”, otherwise that drive may be used for paging file. Also make sure the main drive always has a good bit of free space (20GB+ should be more than enough), so it should be prioritized for the paging file.
