The Dell website does provide the RST drivers. For the Inspiron Laptop 16, the RST drivers are found under the driver category, not the firmware category (which is what the screenshot shows in the article). For the desktop, the driver appears under Recommended drivers.
That being said, I recently did a dual boot install (on an MSI motherboard) with Windows and Pop!_OS and the Linux install went much smoother than Windows. For Windows I had to get the RST drivers and run the setup exe in extract mode in order to get drivers that worked during initial install. And Windows also didn't even include an Ethernet driver by default.
