How to switch the dual video card?

hello, everyone.

I like archlabs very much for its simplicity and elegance . I like it very much, and I look forward to working with you to improve it.

Does archlabs have a dual video card switcher? Where can I find it?

And how to cool the laptop? It is too much heat .

looking forward to your reply. Thank you.
