If using an older kernel a newer one might solve the problem. However in Arch Linux Solid state drive/NVMe it says:
Samsung drive errors on Linux 4.10
On Linux 4.10, drive errors can occur and causing system instability.
This seems to be the result of a power saving state that the drive
cannot use. Adding the kernel parameter
nvme_core.default_ps_max_latency_us=5500disables the lowest power
saving state, preventing write errors.
This sounds like your best first step.

My Samsung 960 Pro is similar to your Samsung 970 EVO. As a reference I’ll include my own system and yours will look similar after repair:
$ lsblk -o NAME,FSTYPE,LABEL,MOUNTPOINT,SIZE,MODEL | egrep -v "^loop"
