ACPI overlaying in Windows ARM

Question

Hi,

I'm Trying to modify ACPI table DSDT file in the Windows 11 Arm System. I'm using iasl tool from ACPICA and able to dump and extract the ASPI DSDT.dsl files. Modified the .dsl file and generated a .aml file which I renamed to acpitabl.dat file and copied to the C:\Windows\System32 directory, Enabled the test signing using "bcdedit /set testsigning ON".

Defined a new i2c device in the .dsl file

Device (VI2C)

{

}

After Restarting I'm not seeing any unknown device in the device manager.

Using the MSFT ASL i cannot compile the dsdt.dsl file it can only compile .asl file.

I'm looking for help and support for overloading the acpi table on windows ARM platform something similar to x86 platform.

Please suggest and point to the technical support team at MSFT for the ACPI loading.

system details

Thanks,
