Based on the available answer, there isn’t a recommended driver workaround here. Fine art matte settings often enforce borders for a reason: edge-to-edge printing can cause ink smearing, reduced image quality near the edges, and in some cases may risk printer issues.

So if the Pro-10 requires bordered fine art settings to use matte black ink, the practical approach is to print with the required border and then trim the print to the final size if you need a borderless result.

In short: no supported alternative is identified in the answers; trimming after printing is the safest suggested solution.
