No 10gb on X550-T2

I have a Proxmox server (8.0.4) with a X550-T2 in it connected to a USW Flex XG. The problem is the 10gb link. It is advertising 10gb with ethtool, but it can't activate this link. I tried to force it in the switch and/or in Proxmox with ethtool and the link is always down at 10gb. It is working fine at 2.5gb and 5gb.

Does anybody has an idea has to why it's not working at 10gb?

My Truenas server is already connected to this switch at 10gb, using a X540.
