It already goes 100Mbit IF you're very lucky and happen to have the node right near your house (and then some poor sap at the other end gets 12).
And no, they cannot upgrade FttN to G.fast, no matter what they tell you. That requires shorter copper lengths than all but the closest handful of houses to the node have. Plus you need everyone on the same technology so that the vectoring (like active noise cancellation) can work.
Gfast drops off a cliff after a few hundred metres, and they have houses connected to nodes a kilometre away. Gfast and Xgfast are only appropriate for Fibre-to-the-curb.

FttN can never be meaningfully upgraded.
