DLSS FG and other Frame generation techs

Hello, i’m in the middle of developing my game and i’ve set up the DLSS plugin to let players use the upscaler and the frame generation. However when i tried to set up another upscaler+frame generation, it doesn’t work unless i set r.Streamline.InitializePlugin to false in the defaultengine.ini, and this cvar is read-only at runtime.
This means that the game requires a restart if i want to change the frame generation technique. Is there a way to not require a restart to change the FG?
