Splat parameters to a cmdlet without unrolling array - powershell

Question

I have this cmdlet:
$dnstype = ,#("Primary","Secondary","Tertiary")
$dnsserver = ,#("192.168.1.11","192.168.1.12","192.168.150.13")
Set-HPEiLOIPv4NetworkSetting -connection $connection -DNSServer $dnsserver -DNSServerType $dnstype
This works fine.
However, I need to splat the parameters, because I am adding parameters depending on the known state of the object (this is because some parameters result in a reset which I'm trying to avoid if possible).
When doing the following the DNS servers are not amended as they need to remain "unrolled" when sent to the cmdlet.
$dnstype = ,#("Primary","Secondary","Tertiary")
$dnsserver = ,#("192.168.1.11","192.168.1.12","192.168.150.13")
$NewDCHPv4Settings = #{
Connection = $connection
InterfaceType = "Dedicated"
OutVariable = "IPv4Set"
OutputType = "Object"
DNSName = $ShortName.ToLower()
ErrorAction = "Stop"
Verbose = $true
}
# Check DNS and amend if required
if ($IPv4Settings.DNSServer -ne $dnsserver) {
Write-Host "DNS server entries not correct, amending"
$NewDCHPv4Settings.Add("DNSServer", $dnsserver)
$NewDCHPv4Settings.Add("DNSServerType", $dnstype)
}
Set-HPEiLOIPv4NetworkSetting #NewDCHPv4Settings
So the question - how do I add the unary arrays to the splat array so that the integrity is maintained and they process correctly?

As in comments, my issue was being cause by the iLO itself/logic rather than the splat being incorrect. My original code does indeed work as intended:
$dnstype = ,#("Primary","Secondary","Tertiary")
$dnsserver = ,#("192.168.1.11","192.168.1.12","192.168.150.13")
$NewDCHPv4Settings = #{
Connection = $connection
InterfaceType = "Dedicated"
OutVariable = "IPv4Set"
OutputType = "Object"
DNSName = $ShortName.ToLower()
ErrorAction = "Stop"
Verbose = $true
}
# Check DNS and amend if required
if ($IPv4Settings.DNSServer -ne $dnsserver) {
Write-Host "DNS server entries not correct, amending"
$NewDCHPv4Settings.Add("DNSServer", $dnsserver)
$NewDCHPv4Settings.Add("DNSServerType", $dnstype)
}
Set-HPEiLOIPv4NetworkSetting #NewDCHPv4Settings
