Which one is better, freezeG or freezeD?

Thanks for your work, simple but effective.
Freezing D&G both work, I wonder which one is a better way, or can we freeze simultaneously both G&D ?
Another question is about manipulating the latent, is that mean we only pass the edited latent to high level layers of StyleGAN and keep the original latent in low level layers?
