Help with dual booting MacOS and Windows

I’m going to address several problems I’ve come across so far so I won’t spam this sub.

Here is my build.

I’m following the Macbreaker guide on dual-booting with separate hard drives. Is the step to create a separate installation USB for UEFI still necessary for windows 10. If so, what can I do if I don’t have access to a windows computer. If not, are there any steps to take to make sure the installation goes well.

Next, even on the lowest setting, the mouse is way to sensitive. I could not find a driver for MacOS on reddragon’s website. What do you recommend?

I am unable to connect to WiFi, and there’s are no Ethernet ports near where my computer is set up. Is there a driver I can install or anything else you recommend?

I am having trouble finding a driver for my gpu. I’ve been getting a lot of conflicting information from my searches.

Anything helps. I am not very tech savvy, so please be as clear and detailed as possible.

Thanks.
