My Dedicated Graphic card shows up in System Info but not in BIO's???

This is a software-controlled hybrid system -- there is no way to control the GPU at the hardware or firmware level.  The software (video driver) handles the GPU.  That's completely normal for this system.

If the system sees the GPU, you do have the nVidia chip.  What you don't have is a true, discrete GPU -- the nVidia GPU is a coprocessor for the Intel GPU -- it cannot by itself render video.  All video data passes through to the Intel GPU on its way to the display screen(s).  

There are some XPS models that have a true, discrete GPU -- the 17" XPS did, with the high-spec RTX 3080, 4060, etc. did.  Lower models are software controlled, as yours is.

I forgot to add the other BIOS screen. How come I can't edit my post above to put that in there? Meanwhile here it is:

For GTX 1650, you can verify its existence in Device Manager or Task Manager/Performance tab.

For system service tag, Dell would not provide support to a system if service tag has been tampered or missing.  However, this system reaches end of life and is no longer eligible for extended support service.

You must decide if you want to keep the system as is and provide self support, or you can return it.  But, if you found a system with the condition that you like, nothing else matter.

So my  nVIDIA GTX1650 is worthless??? Does it do anything at all? First I've ever heard that? Why have it. It was one of the reasons I bought it and to get the i9 CPU.

How about this?
If your Dell dedicated graphics card (nVIDIA GTX1650) appears in your system information but not in the BIOS, it likely means that the BIOS settings might not be configured to properly detect or enable the dedicated graphics card; check your BIOS settings for a "Switchable Graphics" option and ensure it's set to use the dedicated card, or that the dedicated card is not disabled within the BIOS video settings.

The XPS 15 7590 maxes out with a GeForce GTX 1650 built on the newer Turing architecture. 

No mention on any of the reviews or anywhere else about what you said? This was a big review,

no mention there either?

Links please as I'm not seeing what you say on the several reviews I've looked at or anywhere else?

If you're not seeing a firmware option to enable direct video output (which you won't, because it's never been available on 15" XPS systems), the graphics hardware is set up as MUXless -- it's software controlled.

If you're looking for a true discrete GPU, you need an XPS 17 97xx) model with the highest nVidia option (for the 9700, that's the RTX 2060, for the 9730 it's the 4070 or 4080 GPU, etc.).  The lower line GPUs are also MUXless.

Presumably, the existence of the Alienware 15 models is the reason all the 15" XPS models are MUXless.

As for the i9 CPU, it's effectively worthless in the slim XPS 15 chassis -- it's actually slower overall than the i7 because the slim chassis doesn't have the thermal mass to keep it cool enough to prevent throttling.
