Hi @etg80691
You're stuck with what it has.
According to the [https://www.samsung.com/us/computing/windows-laptops/notebook-series-9/notebook-9-pro-np930mbe-k01us/|specifications] the laptop has 8GB of ''on-board memory'' i.e. non removable and there are no extra slots to insert any more.
Here's a teardown [https://www.youtube.com/watch?v=SjHNvEyZH8E|video] if you wish to verify this.
