Yakima's Core Bar roof rack crossbars # Y00421 can be cut to a specific length so long as you can make clean square cuts to allow re-installation of the bar end caps. You will probably also need to file the cuts to make them smooth and safe for handling.
The Yakima roof racks confirmed to fit your 2018 Toyota RAV4 are shown on the page I linked for you. These racks use bar lengths of 48 or 50-inches.
