Start the system by using a live-CD/USB.
Now lets assume the ssd is /dev/sdx and the nvme is /dev/sdy…
as root use:
dd if=/dev/sdx of=/dev/sdy bs=4M status=progress conv=fsync
This will get you a 1:1 copy. After that you can use gparted to adjust the partitions on the target device to your needs.
Edit:
Make sure to double-check the device-names since all data on the target-device will be lost!
