The S150 supports non-RAID mode, but that still leaves supporting a software-based PERC card as a PCIe switch for the 8 or 10 NVME bays behind it. This doesn’t seem to be the case for Miroslav’s system. There’s no special handling of the PCIe bridge/switch in linux where it does work, and there’s growing evidence that this is a case of FreeBSD not handling hotplug ports correctly. Scotthelp
