AMD says that if the GPU isn't supposed to be in the laptop then there's a chance that there might not even be a fix for it which will render the GPU useless.

Ok this is just my opinion and analysis about your AMD Lenovo, I'm not trying to defend Lenovo or anybody or anything.., because my laptop also Lenovo (Thinkpad E330 Model) but it's an Intel and Nvidia dual system gpus, but if that's what they said and that also to conclude that your dual switchable gpus system is not working because it won't switch especially for TS3 (let's focus on TS3 and put aside another game on this subject for now), I'd say the customer service that was talking to you.. don't really know what their saying with they said that "it which will render the GPU useless", which of course your dedicated M230 in this case.
Now to the OP if you doubt that your M230 is not running or automatically switching when needed to be precise, we can double check and even triple check to make sure it's switching as is suppose to, because if it isn't, (1) your Win 10 OS will disabled it automatically in the 1st place for some reasons, (2) to double check, you can see it in your Device Manger >> Display Adapters and right click on both of your gpus to open its properties windows for each gpu, in "General" tab you'll see that your device status is working properly, so from Win OS side perspective side, it saying the opposite from what the customer service was telling you, because if they were correct.. one of the two will be automatically disabled, for this purpose I also attached pic from my Lenovo E330.
Now.. (3) to triple check that it is switching to your M230 and your M230 run well as is suppose to for TS3, as you see in the pic I attached, you see in the red boxes that the 4 digits devices IDs for my Intel HD 4000 and Nvidia GT610M are also there, this mean both of device IDs are registered in my Win registry, and you can do the same in your laptop to see it that both of your device IDs are also there, so it confirms that from Win OS perspective that both are working properly.
Now to interpret this to TS3, you now understand that in order TS3 to be able utilize and run one of your gpus, one of the two of your device IDs need to placed in your GraphicCards.sgr, otherwise TS3 will report to you in TS3 DeviceConfig Found 0 Matched 0 with your primary device ID even if you didn't put any of your device ID in the GraphicCards.sgr, and why is that? Because TS3 followed what it was registered in the Win registry, so what happened when you haven't placed any device ID there, the one that will be reported in DeviceConfig is your primary gpu, so when you put your primary device ID as it was the case earlier, it confirms that your primary gpu that was working at that time.
So because TS3 game engine or program was designed prior to this switchable laptop model era so it's not automatically compatible for your AMD Catalyst software to switch it, you need to remove your primary device ID with your dedicated device ID, and when you finally placed your dedicated device ID there, it confirms that you tell TS3 to use the second device as you remove the primary one, and if the secondary failed to work or render to be precise, your TS3 will failed to load or maybe even crashed.
So if after you placed 666F and your TS3 failed to load or crashed, that would confirm what the customer service was saying to you, but if this not be the case, then what they saying is not true.
