Cannot use dedicated gpu on my laptop

Swiching Graphics Card driver on the Asus Zephyrus G14 Laptop

I believe there is a hybrid driver profile specifically for this sort of AMD+NVIDIA setup listed under Garuda Hardware Manager. You can then run applications on the dGPU using the prime-run wrapper (there are a number of threads on the forum that include how to use this, including with Steam).

Have a read of this.
