Dx12 Multi adapter technology apparently uses your Integrated and dedicated gpus together to get maximum performance but how will this work with desktops since to switch between iGPU and dGPU you have to move your cable and you cant run them simultaneously or I am not getting it right
Will DX12 multi adapter technology work on desktops and how?

You will always have the cable in your discrete gpu. All DX12 multi adapter does is offload some of the processing to your igpu (maybe AA or shadows, who knows). It's software, not hardware. The whole point of this is that you haven't been able to run both your igpu and dgpu at the same time, this lets you use it to assist your dgpu.

It wouldn't be aa or shadows as those are contiguous. The demo that was showing it was just offloading just postprocessing but other separable workloads could be offloaded like physics or some effects. That demo was a year ago and dx12 has been out even longer and we still see no game that is going to support this. It's extra work for devs so don't expect it to be even as many games as physx.
You do not need to switch the cable to run both simultaneously on current desktops. We've seen this since sandy bridge when they introduced quicksync but it's still on to do other things as well. We've been able to run both, just not together to help in games. Computational software or even gpu renderers were already capable of using multiple different gpus (yes even igpus) before even windows 10 was announced.

If it's not showing in device manager, then it's off. I don't know what setting you changed to turn it on but if you didn't do anything then it's off. I don't think you know what quicksync is but it's for video encoding so it's something you aren't doing. It was just an example to how others were using it without having anything connected to it. Same goes for computations or rendering. It does nothing with it sitting there and no monitor on it unless software can use it. But there are no dx12 games that support dgpu+igpu so has nothing to do with games. And you can't have the dgpu work as a passthrough for the igpu without other software to do it.
Well if the intel graphics is there in the device manager under display adapters with a drvier version of 20.19.some other random numbers. Then how come I cant use it I mean in games there is only gtx 970 no intel hd at all in all games its not like the hd one Is better and I wanna use it its just that i wanna know that its there and usable also I see alot of people saying that to use the Igpu your monitor HAS to be connected directly to your Mobo not to your Dgpu

As I said before, you can't use the dgpu as a passthrough and there are no dx12 games that can use dgpu+igpu. Using it without a monitor has nothing to do with games without there being any games with support. If you want to use it in game then you have to connect a monitor to it but then obviously the 970 won't be used. If you use software that can select the gpu for compute then you can use the igpu without a monitor.
