Anyway to make system boot into MacOS rather than Windows

I'm a designer and not overly Mac sophisticated. I am running a 15" MBP 2017 with touch bar. I am set with the newest HDD formating, but when I go into set my boot drive in Windows OS, It doesn't see my Mac OS partition, anyone know if I can boot directly into it rather than needing to hold down control to select Mac OS?

Thanks!
