Installing MacOS on a HDD used for storage?

So I have a 2TB hard drive that I use to store all my files on since my SSD is only 240gb. So I was wondering if I could make a partition on the HDD for lets say 150gb would I be able to install MacOS without having to format the entire drive?

Windows is not installed on the HDD. It is strictly storage
