I don't think consumer boards will have that, finding them on the WS models of z690/790 boards would be rare.
Better to get u.2 to m.2 connector and cable or u.2 to pcie adapter card (this is what I bought from some obscure Amazon seller for 2k).

The u.2 to m.2 connector seems simple enough but the pcie card doesnt seem to have the u.2 board connector, what cable do you need?

This is the one I'm talking about for u.2 to pcie adapter: https://amzn.eu/d/eOyctxs
Lookout for the sellers, most of them are sketchy but some do deliver, the one I got worked for pcie gen3 ssd (its delisted by the seller now but its similar to the above adapter).
U.2 to Pcie Gen4 are not available in India and there are also 2x/4xU.2 adapters on Amazon XD.

Will the M.2 to U.2 adapter work? Is it reliable? I need the PCIE slots, don't know if I can spare them as the boards for the 1700 socket seem to have few PCIE expansions. I am ideally looking for 8-10 SATA, 4-6 PCIE and 1-2 U.2 board for the 13900k, I know such boards exist for the Xeons but they are expensive and don't perform as well for desktop use due to poor single core performance relative to the cheaper 13900k. I looked but couldn't find anything. My options are either try to find a board with at least 4x PCIE and fit everything and use an adapter or go for a Xeon system. Neither looking appealing to me.
 
Now that's tough, even the best z690/790 board won't have enough pci+dmi lanes to cover all that. This treads into building two separate systems.
M.2 to U.2 will work but will be more expensive with adapter+cable but it's doable. Coming to reliability, all these adapters are just dumb connectors and the only thing that will break them is physical damage or using poor quality wires/or long cables resulting in signal degradation.

If you can shell out and build two systems then going for old Xeons is one way but EPYC systems have also seen a reduction in prices for 2nd and 3rd gen so they can also be considered, only con is that board prices start from 40-60k for EPYC but you get more PCI-E lanes than required. Else if you can compromise on 4-6 PCIE to say 2-3 then a second Ryzen build will also suffice.
 
OP you need something like this for M.2 -> U.2 https://www.amazon.com/gp/product/B07VB6L8SJ/ Remember if you get this then in all probability you won't be able to use the MoBo heatsink.

There are quite a few boards with 8 Sata ports, but keep in mind if you use all 8 you will have to sacrifice an M.2 slot.

As for 4-6 PCIE slots, forget it. This board https://www.asus.com/us/motherboards-components/motherboards/workstation/pro-ws-w680-ace/techspec/ has 4 but it has only 3 M.2s

What all do you need to connect to the MoBo?
 
Been reading a little and it seems there is an EVGA board with U.2, is EVGA available in India? Also this board seems to have lower RAM slots and less PCIE. Not looking to build 2 systems, if the adapter works without issue then that is a good choice. Will there be any issues using the OS drive with the adapter in regards to boot etc? Need to connect GPU,Sound card and HBA. Also want 1 extra PCIE for future use.

Doing some reading, now not sure but do you need Windows 11 for w3400/2400 Xeons? Will they not work on Windows 10?

None of the EVGA Z690/790 boards have a u.2 connector.

If you want lot's of PCIe slots for 13900k one option is to use M.2 to Pcie risers. But given your requirements maybe 13900K might not be the right fit due to the platform.

I understood that thats why I am also looking at Xeons. Will the new Xeon w3400/2400 work on Windows 10?
 
After some searching, Windows 10 is supported on the new Xeons so that is an option if needed. Still haven't found a board for the 13900k. Did order some M.2 to U.2 adapters to try and see how that goes.
