Can I still file my claim if I have already signed an agreement with the bank?

Yes. If the judge declares the ‘floor clause’ to be null and void, you can claim even if you have signed an agreement. The same rule applies if you have reached an out-of-court settlement and you are not satisfied with the offer received. Or if they have refused to reimburse your money. In such cases, you can always resort to the courts, to make a claim for everything you are entitled to.
