Convert PDF to grayscale

We would like to use icePDF to convert a color PDF into a grayscale PDF.

We want the text to remain as vector text so we cannot use a solution where each page is rendered to a grayscale image.

Ghostscript offers a method for converting to grayscale (shown below) which sets the color model to grayscale.

I would like to know if icePDF can perform the same function.

[code]
gs -sOutputFile=gray.pdf \
-sDEVICE=pdfwrite \
-sColorConversionStrategy=Gray \
-dProcessColorModel=/DeviceGray \
-dNOPAUSE -dBATCH \
-dAutoRotatePages=/None \
color.pdf
