Provided you don't just blindly accept everything the hardware device displays and actually pay attention to what it is doing, then you can reject the transaction which will prevent it from being signed and broadcast.
I agree with this bold part because if you do not check it carefully it will end up sending to an unknown address.
So always make sure to check the transaction and the hardware wallet carefully before you sign the transaction and I suggest you if you have the fake Electrum wallet installed much better uninstall and clean the PC/Laptop and install the original Electrum to keep your wallet safe.
