How might I permanently disable p.NetEnableMoveCombining?

I can enter the command into the console (p.netenablemovecombining=0), but it resets every time I reboot the engine.

old question, but this is the #1 solution i found to solve the listen/local client animation jitter problem.

to permanently disable p.NetEnableMoveCombining enter it in your project’s DefaultEngine.ini

[SystemSettings]
p.NetEnableMoveCombining=0
