Dmesg reporting lots of errors apparently relating to my NVidia card and Realtek RTL810xE PCI Express Fast Ethernet controller?

On a DELL Inspiron 5593 laptop I am running:

$ uname --all
Linux debian 6.1.0-15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.66-1 (2023-12-09) x86_64 GNU/Linux

dmesg logs are flooded by such error messages:

[ 9514.141680] pcieport 0000:00:1d.0: AER: Multiple Corrected error received: 0000:01:00.0
[ 9514.141723] r8169 0000:01:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
[ 9514.141728] r8169 0000:01:00.0: device [10ec:8136] error status/mask=00000001/00006000
[ 9514.141734] r8169 0000:01:00.0: [ 0] RxErr (First)

which I can’t understand because I am not using that wired connection at all and the wireless connection to the Internet starts misfunctioning.

I’ve got a:

$ lspci -v

00:02.0 VGA compatible controller: Intel Corporation Iris Plus Graphics G1 (Ice Lake) (rev 07) (prog-if 00 [VGA controller])
Subsystem: Dell Iris Plus Graphics G1 (Ice Lake)
Flags: bus master, fast devsel, latency 0, IRQ 126, IOMMU group 0
Memory at 90000000 (64-bit, non-prefetchable) [size=16M]
Memory at 80000000 (64-bit, prefetchable) [size=256M]
I/O ports at 4000 [size=64]
Expansion ROM at 000c0000 [virtual] [disabled] [size=128K]
Kernel driver in use: i915
Kernel modules: i915

Basically I have a 7 GiB large disk to do intensive data processing, but in order to use that faster storage space I need to troubleshoot those errors.

How do I?
