There is a method to disable AMT in HP BIOS using one of their tools. You can pull down the tool here:
On the page, there is also an HP BCU User Guide link, you can use this for reference.
1. You'll need to verify the settings on each of the computers because the verbiage in the BIOS differs from model to model. You can run the tool and do a "get" command on each of the models to find out the correct verbiage.
2. Once you find the correct verbiage, you would remotely call WMI to disable AMT on the system. You can use powershell to do this.
An example (this was for an unconfiguration):
$HP_Bios = Get-WmiObject -Namespace root\hp\instrumentedBIOS -Class HP_BiosSettingInterface
$HP_Bios.SetBiosSetting('Unconfigure AMT on next boot', 'Apply')
$HP_Bios.SetBiosSetting('Show Unconfigure ME Confirmation Prompt', 'Disable')
An example for AMT for this specific model (800G2)$HP_Bios = Get-WmiObject -Namespace root\hp\instrumentedBIOS -Class HP_BiosSettingInterface
$HP_Bios.SetBiosSetting('Active Management (AMT)', 'Disable')
If someone has:
1. Physical access to the system
2. Is knowledgeable enough to access MEBx
3. MEBx password is set to default and has not been changed.
then they would be able to re-enable AMT using the default admin password.
There are three ways to change the digest admin default password (in order of simple to complex):
1. Physically on the system, accessing MEBx and changing password.
2. Configuration via USB Key, which begins in section 1.4.2 of the SCS User Guide - Physical access to the system is required for this method.
3. Remote Configuration (best solution if you have many systems or if they are remote but are on your domain). More details begin at section 1.4.4 of the SCS User Guide.
There is no other method for changing the default admin password.

Question 6 is most appropriate for your question.

I have looked at your pdf link. It seems the 1.4.4 section you referenced says
"To use this method, the Intel AMT device must have at least one active hash
certificate defined in the Intel MEBX. If the manufacturer does this before he sends the computer out, then you
can configure these computers remotely."
So the next question is, what if the manufacturers did not configure this? Does that mean that we can not do it remotely?
For remote configuration, a specific AMT certificate from one of the certificate authorities is required. As mentioned in the previous post, there is only one way to perform a remote configuration where the MEBx password can be changed, which is the aforementioned method. You will be unable to perform this change remotely without one.
If an AMT certificate was purchased from a qualified Certificate Authority, referenced here:
The certificate would reside on the RCS Server in the certificate store of the service account running the RCSServer service. Once you open the certificate snap-in for that account, you will find the certificate in the personal store. You would then be able to look at the certificate subject and match it against the OU string: Intel(R) Client Setup Certificate
or the OID under Enhanced Usage AMT OID: 2.16.840.1.1137184.108.40.206
I don't quite understand the statement as WOL works with AMT but there are requirements:
1. Must be an Intel NIC
2. Must be wired
3. Must be enabled in the BIOS
