Arduino uno . Nextion LCD and pushbuttton with interrupt


I read that , in order to use Nextion LCD with an Arduino Uno, it uses pin 2 and 3 (TX and RX).

Due to the fact that I need an interrupt routine and that the pins dedicated to interrupt are the same 2 and 3 how can I install an emergency push button that uses the interrupt while using the Nextion LCD?

Or is it possible to connect the LCD to pin 0 and 1 ?

Thanks for any help.
