Advanced Optimus Not Working

I have a Lenovo Legion 5 2021 (5800H, RTX 3070) that's running Windows 11. I enabled Advanced Optimus from the NVIDIA Control Panel but it does not switch to the dGPU when I launch games like CS:GO, Portal 2, and Brawlhalla .It does work with Rocket League and Fortnite, however. (Could this be an Epic Games / Steam thing?)

 

I've tried switching on Automatic Display Switching, which did switch the graphics to the dGPU but would crash the games.

 

All my drivers and firmware are up to date. Does anyone have any idea how to fix this?

CPU: Intel i7-6700k - GPU: EVGA GTX 1080 FTW - Motherboard: Asus Z170-A - RAM: Vengeance LPX DDR4 16GB 3000MHz - CPU Cooler: Corsair Hydro GTX H110i - PSU: EVGA SUPERNOVA 650W P2 - Case: NZXT H440 White/Black - OS: Windows 10 Home - Mouse: Logitech G502 - Keyboard: Corsair Strafe Cherry MX Red RGB
