Is there a parameter I can assign to the part to remove it from the DRC check?
put your graphics on a different (custom) layer, and then don't DISPLAY that layer when you run the DRC.
(DRC only checks the layers that are currently displayed.)
When you generate gerbers, add your custom layer to the list of layers included for the appropriate "final" layer.
(For example, the BOTTOM copper layer might normally include layers BOTTOM, PADS, and VIAS. You'd use a new CAM file that output
BOTTOM, PADS, VIAS, and BOTCOPLOGO to that gerber...)
(yes, this means you can't just send the .BRD file somewhere and expect correct results. You probably shouldn't, anyway.)
