Specific curves to install

I found this in the “Read Me” Piezography Pro Curves for Piezo Pro customers only.

“A third folder is called “NoGCO” and this enables printing of the image without any GCO at
all to then gloss-optimize the print later on. We do not recommend this method as the
curves were built with GCO to be printed at the same time and lack of GCO could
compromise the image quality”
How can I add these ?
