Yes, you can use those pins like regular digital pins on the Uno. They are numbered 0 and 1. That is... provided you do not try to use Serial.

and the component wired to this pins can interfere with sketch upload. and if one of this two stops working then no serial upload will be possible. – Juraj Jun 17 '20 at 19:08
