As said, inductance on the source slows down the switching.
Also, for the same di/dt you get the same voltage spike due to leakage inductance. Except now its a negative voltage on the source instead of a positive voltage on the drain.
Any reduction of DS voltage stress is going to be due slower switching caused by the added source inductance. If this is an issue, you might as well just slow down the gate drive with a gate drive resistor, that's more adjustable.
Additionally, Treez/ocset, if you are going to keep creating alt accounts to get people to do your job for you consider changing your phrasing so its not immediately obvious
