No SET-Switch Team possible on Intel X710 NICs?

Hello,

we have lot of servers from different vendors using Intel X710 DA2 network cards.
They work fine in standalone and they work fine if we create switch independet teams using Server Manager, Regardless of Dynmic or Hyper-V Port.
But sadly we can't use these teams in Server 2025 because have to create SET-Switch Teams instead.

But as soon as we create an Hyper-V SET-Switch Team with X710 cards, they have limited to no network communication.
They still can communicate with some servers, are slow with some ohters, and can't communicate with some at all.
Especially communication to other servers, which also use X710 cards with SET-Switches, is zero.

SET-Teams with other cards like E810 work just fine.

I've read several times that the X710 cards just wont work with SET, even since Server 2016.
But I can't really give up on this, since we would have to replace a lot of them.
We have tried to disable a lot of features like VMQ, RSS, RCS... but couln't make it work.
Firmware and Drivers are the most recent, but it happens with older versions too.

Does anyone have a solution?
Thank you!
