Trending @Accenture; Notice period

Yes, you can. While filling you exit form on service now you have the ability to choose a date lower than 90 days.
However, it will be adjusted with your earned leaves or you will have to pay for those days. i.e. buyout option.

I am already serving my notice period, hence speaking from personal experience.

Depends on your manager and if you on bench

I have asked my HR for notice period reduction as I am in bench but she doesn't agree at all. It's been 50 days if NP now and still nothing 🥲

You can may be ask if there is any buyout option

Check for leaves adjustments.
