For the ST, roof rails were standard for 2020, optional in 2021 and 2022, then standard again in 2023 and 2024 according to the order guides. Probably made optional due to the pandemic for some reason. The crossbars were always accessories. I have read a thread about an owner taking their rails off, but I would think those would be rare cases. You could get a copy of the window sticker to verify they were not on from the factory, but more than likely they were never ordered with the vehicle when new since they were optional in 2022.
