Unless you’re doing a Low-Level format of some sort, it should take mere seconds to change the format from exFAT to NTFS.

Are you using Disk Management in Windows, or using some other tool / OS?

In Windows Disk Manager, You just find the disk in the bottom half of the window, select the partition you want to format, right click it and select “Format…” and set the options accordingly.
