You can clone from the original drive to the NVMe, yes - the only thing to be careful of is to ensure you disconnect the original drive before booting the clone for the first time. Macrium Reflect is among the easier tools to use. Also note that the Samsung 980 drives are PCIe 4 -- they will work with your system but at the lower PCIe 3 speed.
