After following this post: https://www.redhat.com/archives/dm-devel/2008-September/msg00235.html

I have prepended the following to /lib/udev/rules.d/95-multipath.rules:

#Weed out the linear map.
KERNEL=="dm-*", PROGRAM=="/sbin/dmsetup table -j %M -m %m", RESULT=="*linear*", OPTIONS="last_rule"

# And block devices that come from usb:
ACTION=="add", KERNEL=="sd*", SUBSYSTEM=="usb", OPTIONS="last_rule"

This prevents /dev/sdi from showing up under lsblk completely and is now missing as a block device completely:

$ ls /dev/sdi*
ls: cannot access /dev/sdi*: No such file or directory

I think this is some progress, but not working as intended yet.
