No, the court or the police have released you on bail and failure to comply with the conditions or requirements of the release could lead to your arrest. Signing early, late or not at all is a breach of bail and it is more than likely that you will be arrested and put before the next court.
If you want to change your police bail conditions, you or your solicitor should contact the custody officer at the station from which you were bailed - before your original bail date. To change your court bail conditions, you will have to speak to your solicitor before your bail date - who may go to court on your behalf.
Note, your request will not automatically be granted. The custody officer and court will consider the application before making a decision on whether or not to amend the conditions.
