Nagios Core R630 Controller check reporting SATA controllers as "Unknown"

The Controller component check is returning this:

Total Instances: 3, Healthy Instances: 1, Warning Instances: 0, Critical Instances: 0, Unknown Instances: 2
#1 Status = OK, FQDD = RAID.Integrated.1-1, CacheSize = 1024.0 MB, FirmwareVersion = 25.5.6.0009, Name = PERC H730 Mini
#2 Status = Unknown, FQDD = AHCI.Embedded.1-1, CacheSize = 0.0 MB, FirmwareVersion = Not Available, Name = C610/X99 series chipset sSATA Controller [AHCI mode]
#3 Status = Unknown, FQDD = AHCI.Embedded.2-1, CacheSize = 0.0 MB, FirmwareVersion = Not Available, Name = C610/X99 series chipset 6-Port SATA Controller [AHCI mode]

Which is being reflected in the "System" and "Subsystem" check as a Warning.

How can I suppress this?
