All models can have a 10 Gbit Ethernet solution, it is an option you can choose in the Apple Store.
Optional 10 Gbit Ethernet (Nbase-T Ethernet with support for 1 Gbit, 2.5 Gbit, 5 Gbit and 10 Gbit Ethernet with RJ-45 connector).
You can configure this on any 2023 Mac Mini at Apple. With 1 Gbit, the model costs 110 francs less. Since you can't configure devices at Digitec, I would look at the desired configuration directly at Apple, and it shouldn't be more expensive in terms of price.
