It doesn't work correctly, no. Apple stopped allowing signed Nvidia drivers starting with Mohave and the drivers from Apple for the device are buggy and cause issues.
Maybe the driver issues you experience are resolved in more recent macOS versions. I run macOS 10.14.6 on a Mid 2014 MacBook Pro with GeForce GT 750M. No issues here.
possibly... I don't actually use my laptop, and when I did my hardware refresh a couple months ago, I went linux from my older hackintosh (nvidia gtx 1080)
