A WMS returns a rendered image (raster), and it's not usually possible to remove individual features based on pixel values alone.

A couple of alternatives:

  • Talk to the publisher of the WMS and request a custom layer that corresponds to your requirements
  • Use a WFS with the same data, if available, then you'll get the vector features with attributes and can filter and style them yourself, e.g. using the MapnikRasterizer.
