At this point, that might be easier.

# cat /etc/multipath.conf
defaults {
    user_friendly_names     yes
    queue_without_daemon    no
}
devices {
    device {
        vendor       "LIO-ORG|SCST_BIO|FUSIONIO"
        product      ".*"
        features     "1 queue_if_no_path"
        path_checker tur
    }
}
blacklist {
    device {
        vendor  "ATA"
    }
    device {
        vendor  "QEMU"
    }
    device {
        vendor  "Linux"
        product "scsi_debug"
    }
    devnode     "^nullb.*"
}
blacklist_exceptions {
    property        ".*"
    devnode         "^nvme"
}
# echo reconfigure | multipathd -k
multipathd> reconfigure
ok
multipathd>
# multipath -ll

So, no output.
