It all depends on the facts of the case. The court has the power to extend time for filing of the rejoinder. You can make a request. If you have a genuine reason for extension of the time for filing the rejoinder, the court may allow it.
But, please also remember that it is not necessary always to file the rejoinder. If only there is a necessity to counter certain averments made in the counter-affidavit / written statement of the respondent / defendant, you should file the rejoinder; otherwise, it is not mandatory and there is no need to file it as a routine exercise.
