Programmatically set the channel-configuration mask for the full-range speakers

Is there a way to programmatically specify which speakers is a full-range speaker? I get get the property of the PKEY_AudioEndpoint_FullRangeSpeakers using the following code:

IPropertyStore *pStore;
hr = pDevice->OpenPropertyStore(STGM_READ, &pStore);
if (SUCCEEDED(hr))
{
	LPWSTR pwszID = NULL;
    
	PROPVARIANT varName;
	PropVariantInit(&varName);

	PROPVARIANT eventDriven;
	PropVariantInit(&eventDriven);

	PROPVARIANT speakerMask;
	PropVariantInit(&speakerMask);

	if (SUCCEEDED(pStore->GetValue(PKEY_Device_FriendlyName, &varName)) &&
	SUCCEEDED(pStore->GetValue(PKEY_AudioEndpoint_Supports_EventDriven_Mode, &eventDriven)) &&
	SUCCEEDED(pDevice->GetId(&pwszID)))
	{
		//pStore->GetValue(PKEY_AudioEndpoint_PhysicalSpeakers, &speakerMask);
		pStore->GetValue(PKEY_AudioEndpoint_FullRangeSpeakers, &speakerMask);
	}
...

But the property is read-only and I can't use SetValue() to set the key.
Does anyone know how to set this property?
