Weird Laptop Issues. Am I Overloading My CPU Lanes?

I have a dell Precision 7530 with an i9-8950HK which has 16 PCIe lanes according to Intel's website. Its other specs are 64GB RAM in 4 modules, Quadro P2000 graphics card, 3 M.2 NVMe drives, external GPU with 2080TI connected to thunderbolt 3 and some peripherals connected to powered USB hub (Logitech keyboard, mouse, cd/dvd drive, and 1 usb hard drive). I have been having issues where my USB devices seem to either keep disconnecting and connecting as if my USB controller is being reset, my sound is becomes gargled, and if my keyboard is working it acts like keys are being suck for a sec or two. Try to backspace once and an entire line is removed etc. I have tried different USB hubs, and peripherals, but it does not help. I have installed Windows 1803 and 1909 dozens of times, rolled firmware back and forwards etc. Dell even sent me a replacement system board with integrated CPU to test with no success.  I connected my older Dell 5510 with a Xeon E3-1505M v5 CPU in the exact same setup minus internal components and it has been working perfectly for weeks. I am wondering if i am just overwhelming my CPU lanes or something. There is not any documentation for the dell system board to tell me what lanes and bandwidth go where. I did a lspci command and attached. I am wondering people here who are much smarter than me can tell me either way or guide me to what the issue may be.

Did you try the external GPU at the same time with the old laptop? All the external stuff are connected to the chipset which means low speed (the GPU can max out chipset bandwidth without much effort)

Usually laptop gpus run at x8 to save lanes so you have at least 8 left for 2 nvme drives

Yes same eGPU and card and is connected to old laptop with no issues. The old laptop has an internal Quadro M100M GPU vs the internal Quadro P2000 that the new laptop has. Not sure on the lane difference between the two.

Yes so im running an eGPU via thunderbolt 3 so i think that is limited to 4 lanes not sure if each of the 2 tb3 ports share that 4 lanes or if they are split. I have no idea what the internal GPU is running at but add 3 m.2 drives and i assume the USB ports need some lanes as well.
