Validity of 498 cases after mutual divorce

My friend is a Hindu by religion and married another Hindu lady in 2014. Both are in Govt. service. They got married by special marriage act in the year 2014. My friend's wife has filed a case against him under section 498 in the year 2015. Later she filed another case of Domestic violence against him seeking for alimony in the year 2015. She filed another criminal case against him in the year 2016. My friend has filed a case for contested divorce against her in 2018. After that, the case of Domestic Violence has been dropped in the year 2018 since she realized that she can’t get any alimony since she is a Govt. servant. She has also withdrawn the criminal case filed in 2016 against him. Now, they are asking my friend to withdraw the case of contested divorce and go for a mutual settlement. However, the outcome of the case filed under section is 498 is unknown. Now, my question is that whether the case under section 498 will be automatically dropped if they are mutually divorced?
