In the Artwork Control Form, Film Control section you can use the option, Suppress Unconnected Pad. You can set this option individually for each layer. It does not remove the pads from the Allegro data base, it only removes them from the Gerber artwork. There is no need to restore the via pad because it is never removed from the Allegro database. For additional control you can take advantage of the Optional/Fixed switches in Pad Designer. Choosing the Fixed setting in Pad Designer prevents suppression of the pad in the Gerber data even if Suppress Unconnected Pad is turned on in the Artwork Control Form.
