For AI stuff you’d want something with at least an RTX 4060. AMD GPUs for laptops are not great and most of them don’t support AI. Any card that’s good for AI will also be good for gaming so you’ll be fine there.
You probably want something with 32gb of ram, too.
As for pulling out the wifi card, there’s no need. Most laptops let you disable wifi through the BIOS, completely disabling it at a system level.
Dual booting works on anything.
Generally I’d recommend Lenovo Legions, ASUS ROG stuff. If you’re rich you can also look into Razer I guess.
