Thx, this solution has helped me too) Blessing you!

You're having trouble installing more than two NVMe drives on your Synology DS1823xs+, DS1821+, or DS1621+ NAS. This is because these models have a hardcoded power limit of two NVMe drives. So I think there are two workarounds: Replace the two files /usr/lib/libsynonvme.so.1 and /usr/syno/bin/synonvme with the versions from DSM 7.2-64570-U2. Use a custom device tree to override the hardcoded power limit. That's all:)
