Assuming you are write protecting /etc for a reason, simply mv
everything in /etc/lvm to your new location and replace the lvm dir
with a lvm symbolic link to your location.

In the far past when booting with RO devices I had lots of links in
/etc/ pointing to files that were not on the read-only and/or
writable-but-lost-on-boot(overlay) device.
