Wiping disks is usually lots of dirty buffers and a slow dequeue of
write I/O to the target.  free(1) and /proc/meminfo may illustrate the
effect.  You might try the nocache package, or dd with conv=nocache.

If that does nothing, well and good.  If it helps, then it points at
memory as a contributor to the problem.

By the way, do the kernel reports of NVMe aborts show up in any way
higher up the stack, like in user-space failures?
