Trending @Capgemini; Serving Notice Period!!

I have put down my papers yesterday and the notice period is 90 days. I am stuck in a toxic project. I don’t have any dependency just one Jira ticket and it is in blocked status. Do I need to regularly login and do the work? I have other works to attend to and don’t want to work during the notice period. Will this affect my reliving letter or anything if manager says so? Please let me know!!
