Permanently disable power management for trackpad (using Powershell or WMIC)

Question

I kept having a problem with my Dell XPS 15 going into a sleep state (disabling the display) when my computer was left unattended for more than 10 minutes. When the system resumed, the touchpad would not work properly. I first thought it was a hardware issue but I found that shutting the lid down momentarily and lifting it up again would resolve the immediate problem so I figured that it was a software/driver issue. However, updating firmware and drivers did not resolve the problem.

Other users reported the same issue but I found this solution (originally from Dell XPS 15 7590 trackpad doesn't function well after sleep/screen turn off - r/Dell) worked for me:

1. Open the Device Manager.
2. Under System devices, open Intel(R) Serial IO I2C Host Controller - A369.
3. In the Power Management tab, uncheck “Allow computer to turn off this device to save power”.

Unfortunately, every time Windows 10 updates itself (around once a week), the power management settings are restored to their default settings. The problem returns and I have to repeat the above steps. Is there a PowerShell command – or even a WMIC command – that I could use to automate this (e.g., run every time the computer boots)?

Typing Get-Help power returns the following results but they are only applicable to network or storage devices:

Name                              Category  Module                    Synopsis
----                              --------  ------                    --------
Enable-NetAdapterPowerManagement  Function  NetAdapter                …
Set-NetAdapterPowerManagement     Function  NetAdapter                …
Get-NetAdapterPowerManagement     Function  NetAdapter                …
Disable-NetAdapterPowerManagement Function  NetAdapter                …
Enable-StorageEnclosurePower      Function  Storage                   …
Disable-StorageEnclosurePower     Function  Storage                   …

Likewise, Internet searches only return results applicable to network adapters.

Note: I could avoid this problem by configuring the power management to never turn off the display but for environmental and practical reasons, I would prefer to keep this setting.
