Convert local PowerShell commands to Cim-Instance for remote administraton

The following PowerShell code works locally but I have not been able to convert all of it to use CIM commands. I have been unable to convert the first three queries to CIM. The reason I need to use CIM is because that is how my network currently allows for PowerShell remote access. The test computer has the latest SCCM Client installed. 

# Check all locations that would contain a pending reboot flag
$RebootPending = $false
$RebootPending = $RebootPending -or ([wmiclass]'ROOT\ccm\ClientSDK:CCM_ClientUtilities').DetermineIfRebootPending().RebootPending
$RebootPending = $RebootPending -or ([wmiclass]'ROOT\ccm\ClientSDK:CCM_ClientUtilities').DetermineIfRebootPending().IsHardRebootPending
$RebootPending = $RebootPending -or (@(((Get-ItemProperty("HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager")).$("PendingFileRenameOperations")) |
      Where-Object { $_ }
  ).length -ne 0)
$RebootPending = $RebootPending -or (
  @(Get-WmiObject -Query "SELECT * FROM CCM_SoftwareUpdate" -Namespace "ROOT\ccm\ClientSDK" |
      Where-Object {
      $_.EvaluationState -eq 8 -or # patch pending soft reboot
      $_.EvaluationState -eq 9 -or # patch pending hard reboot
      $_.EvaluationState -eq 10 } # reboot needed before installing patch
  ).length -ne 0)

I have managed to convert the last query to Cim but I cannot seem to determine how to convert the other three queries to Cim

Converted Query:

$RebootPending = $RebootPending -or (
  @(Get-CimInstance -CimSession $($Computer.CimSession) -Namespace 'ROOT\ccm\ClientSDK' -Query "SELECT * FROM CCM_SoftwareUpdate" |
      Where-Object {
      $_.EvaluationState -eq 8 -or # patch pending soft reboot
      $_.EvaluationState -eq 9 -or # patch pending hard reboot
      $_.EvaluationState -eq 10 } # reboot needed before installing patch
  ).length -ne 0
)

You can use the Invoke-CimMethod cmdlet if you want to use CIM sessions. For the first two items in your example, call it as follows:

Invoke-CimMethod -ClassName 'CCM_ClientUtilities' `
                 -CimSession $Computer.CimSession `
                 -MethodName 'DetermineIfRebootPending' `
                 -Namespace 'ROOT\ccm\ClientSDK'

You will get an object back like this:

DisableHideTime     : 01/01/1970 00:00:00
InGracePeriod       : False
IsHardRebootPending : False
NotifyUI            : False
RebootDeadline      : 01/01/1970 00:00:00
RebootPending       : True
ReturnValue         : 0
PSComputerName      :

For the Get-ItemProperty example, call it slightly differently:

Invoke-CimMethod -ClassName 'StdRegProv ' `
                 -CimSession $Computer.CimSession `
                 -MethodName 'GetMultiStringValue' `
                 -Namespace 'ROOT\Cimv2' `
                 -Arguments @{hDefKey=[uint32]2147483650; 
                              sSubKeyName="SYSTEM\CurrentControlSet\Control\Session Manager"; 
                              sValueName="PendingFileRenameOperations"}

The output will be an array of strings like this:

sValue
-----
{\??\C:\ProgramData\Microsoft\...
