Deltagen and muliple graphic cards

We have a computer with two graphic cards: NVIDIA RTX A6000 and NVIDIA T400.
Deltagen 2025 refuse to start when both graphics cards are enable.
When I disable the NVIDIA T400 card it works fine.

Any settings for Deltagen that's needed to be done to be able to have both cards activated and run Deltagen.

DeltaBatch can open while both cars are enable....
