Need help with Game Optimizer

I just got the LG C1. I can't seem to find a way to change any of the settings in the game optimizer. I bought the TV specifically for the 120hz refresh rate. I also can't find a way to turn VRR on. I'm playing on PS5. I have all the appropriate setting turned on in the PS5 settings, I'm using an HDMI 2.1, and I'm playing a game I know for a fact supports 120hz. Any help would be greatly appreciated. I can't find any info online.
