So you are on a rat of ECB +1.75% ? Is that correct?
This is not a very valuable tracker, so you should not worry about giving it up.
Your LTV is <50% , so here are the rates available to you.

These rates are odd as are all mortgage rates. The variable rates should be lower than the fixed rates in a period when market rates generally are expected to fall.
So I would expect the fixed rates to fall but there is no guarantee.
A variable rate below the ECB rate makes no sense so maybe this will be increased.
But, on balance, I would just switch the tracker bit to the variable rate.
