3.73 eLSD, do i need the friction modifier?

[Av8r]

I did some brief searching and didn't see anyone asking this question.

I have a 2019 with the HD tow package. We are right at 41k right now and we do a lot of towing a camper. Just want to do some preventive maintenence.

Do I need to add the friction modifier since this is a electronic LSD? I did not see it listed in the manual.

Thanks

I also found similar information in the 2021 Expedition Manual, Which I assume is the same rear axle / locker.
