Ubuntu 22.04 server, Intel x550, advertised speed not correct

The network card Intel X550T installed on an Ubuntu server 22.04 does not advertise all the available speeds, therefore (if that is the reason) the auto-negotiation fails to connect to the speed available (the source is a 2.5GB connection):

Supported link modes:   100baseT/Full                        1000baseT/Full                        10000baseT/Full                        2500baseT/Full                        5000baseT/FullSupported pause frame use: SymmetricSupports auto-negotiation: YesSupported FEC modes: Not reportedAdvertised link modes:  100baseT/Full                        1000baseT/Full                        10000baseT/FullAdvertised pause frame use: SymmetricAdvertised auto-negotiation: YesAdvertised FEC modes: Not reportedSpeed: 1000Mb/sDuplex: FullAuto-negotiation: on

What should I do, after looking for solutions it seems to be a driver issue, but on the other hand it seems that the kernel in Ubuntu 22.04 should fully support this card ?

Edit:Following @waltinator suggestions, I modified the speed of the card by running:

sudo ethtool -s <name_of_card> speed 2500

The command above raises the speed to 2.5GB as expected.However, I could not turn off the auto-negotiation (which seems recommended from @waltinator comment); if I run the command:

 sudo ethtool -s <name_of_card> autoneg off speed 2500 duplex full

or:

sudo ethtool -s <name_of_card> autoneg off speed 2500

or:

sudo ethtool -s <name_of_card> autoneg off

there is no error but no effect, speed and auto-negotiation are not changed.

Edit 2:After some testing, changing the link mode with the command above leads to random disconnections.Maybe turning auto-negotiation off would solve this, but trying to turn off auto-negotiation on the card has no effect (I suppose the auto-negotiation parameter cannot be turned off on the card if the switch requires auto-negotiation, and I am not allowed to change that on the switch).
