9800X3D Undervolt

[ste-sim2x9]

Hey guys i've just built a new system with a Ryzen 7 9800X3D, ASUS TUF Gaming A620M-PLUS WIFI and Crucial Pro DDR5 RAM 32GB Kit (2x16GB) 6400MHz CL38. Now i want to undervolt the cpu to lower the temp but ran into a problem i'm hoping for some guidance. I've been trying to follow this video on youtube but can't find curve optimizer, i found precision boost overdrive that is show in the video but the guy tells us to select advanced in the precision boost overdrive box but that isn't there. I've used f9 on my keyboard to use the search feature in the bios and typed curve but doesn't show.

I'm on the latest motherboard bios.
