Dark Mode as default?

I’m loving the new dark mode settings, I had something very hacky setup and this will be way cleaner. My only question is that the video says Light Mode is the default, I’m wondering if we could made dark mode the default?
My site was originally designed in dark mode, and its where my branding really looks its best, I want to add the option of light mode for those who prefer it but if no preference is stated, or if it prefers dark mode then dark mode should be shown.
