hprest.exe type HPBios not available

I am using hprest.exe to set different Bios settings like ServerAssetTag which are located at the type HpBios.1.2.0

Now i have a problem with one ProLiant ML350 Gen9 out of 10, where hprest says that the type HPBios. is not available: Unable to locate instance for 'HPBios.'

If I use the command types than the problem ML350 Gen9 returns this:

hprest > types
Type options:

And we see HPBios.1.2.0 is missing, on an other ML350 Gen9 with the same Bios Version, ILO Version and UEFI enabled i get following output via hprest types:

hprest > types
Type options:

PowerMetrics.0.11.0
ServiceRoot.1.0.0
SessionService.1.0.0
SnmpService.1.0.0
ThermalMetrics.0.10.0
VirtualMedia.1.0.0

So this types are missing on the problem Sever:

HpBaseConfigs.0.10.0
HpBios.1.2.0
HpBiosMapping.1.2.0
HpServerPciDevice.1.0.0
HpiSCSISoftwareInitiator.1.0.0

Would be nice if someone can point me in the right direction why this type is available on 9 of my 10 ML350 Gen9?
(I already tryed reflash 2.30 ilo4 firmware and reset ilo to factory defaults - nothing helped)

Thanks a lot!
