Yes, this is possible. You can try if you get sufficient black opacity with the original Epson ink or you can fill UV black ink just into the black ink cartridge. Then you can use the printer to print films for UV exposure and also make color prints.
We recommend to install the PrintFab 30 day trial version which is available for download at www.printfab.net -> link "Download".
Here are the recommended PrintFab settings for halftone printing with the Espon SC-T3170X printer:
In the macOS print dialog, section "Printer Features" -> "Special Settings Screen Printing" it is important that you select "Halftone Screen Mode"="Single Black" (for single black ink) or "Multi Black" (for an ink set with multiple black cartridges). Here you can also set the ink amount, the halftone size and angle:
