Can I use pre-trained models in the repo?

Hello:
I want to know if I can use the repo to convert some pre-trained models to the models which can be used by the repo? For example, Nvidia StyleGAN3, they have a number of pre-trained model in .PKL format.
Can I use their pre-trained model (.pkl format) in the repo to make image prediction?

If yes, please give some general instructions on how to start.
By the way, I am using Visual Studio 2022 in Windows 10 (version 21H2).
Thanks,
