7550 gpu upgrade possibilities

I have got a dell 7550 with a t2000 gpu and was wondering what upgrade posipossibilities there are. These are from the factory these were delivered up to a rtx5000 card.
now there is a driver update ( 31.0. 15.5346, A30 ) for my laptop in which the rtx A5000 is also mentioned. could I upgrade my laptop to a rtxA5000 or is the rtx5000 the maximum?

Kind regards,
