CRB ARL-S original drivers - networking seems to be unstable after clean W11Pro reinstallation

[JiriValenta]

Hello I have here "CRB" (customer Reference Board) machine identified by:
S/N: GPARDV4170011
Product Code: DTAR3SEWEB
CPU S/N: D3HS425301344
CodeName: Arrow Lake-S External
CPU/Chipset or SoC: ARL-S/ MTP-S PCH
BoardName: MTL-S/ UDIMM 1DPC SO2
Phase: Beta

It needed reset and WinRE failed, so I installed clean Win11 Pro from MS and a lot of HW components seem to not have driver (expected). Unfortunately it affects probably networking performance - it seems to be very unstable in transfer speeds (iperf3 tests).
I tested DSA - it found and installed only GPU driver.

Is there some way how to get original drivers? Or even better installation media for this machine? Unknon HWIDs are in attachement.

Thank you!

Good morning, Poojitha
thanks for reply. I'm not sure how to identify more than by Serial Number, which is in original post, but I'll try my best.
I found SSU utility - maybe that could help. In attachement is an output from it.
I'm also attaching photos of Intel labels on case.
The address where it was sent/delivered is:

Karlovo náměstí 17
Prague 2
Czech Republic

Now is the comapny named as Chaos Czech s.r.o. Before it was probably Corona or Corona Renderer. I'm here new IT administrator and I'm not sure how these things work here in this way.  You can reach me also at company address jiri.valenta@chaos.com
Original adresee is probably Martin Šik.

Best regards
