No u cannot ignore the density error. U need to add dummy metal inorder to avoid this error.

Re: DRC--------urgent

Metal density errors

These errors generally occur when a metal layer does not have the required metal density. Refer to the LEF file for the particular layer and look at the metal density value specified for that layer.

You need to do metal fill to avoid such errors. This is generally done at the later stage of the design process.
