LVM/MD take control of a block device (usually a partition), so any info
in that block device can't be used for your purpose.  IOW you have to
put the info somewhere on the disk *outside* of the partition used by
LVM/MD.

I can see a few different options:

- Use some disk-specific tool to change the disk's serial numbers.
  I'm not sure how common such tools are, they're probably
  manufacturer-specific and proprietary; my intuition tells me to try
  any other way first.

- Use partition labels and/or partition UUIDs: contrary to filesystem
  labels, these are not stored inside the block device but inside the
  partition table.  They don't exist in the old MBR-style partitions,
  but they do in GPT (GUID Partition Tables).

- Use an additional tiny dummy partition in which you can put any info
  you like.
