Unable to select tianocore with RW Legacy

I have enabed dev mode (Without debugging features), ran the mrchromebook script in the VT-2 terminal successfully, pressed 1 to install and update the script, shut down my Chromebook, plugged in my USB, turn on and hit Ctrl + L for RW legacy, pressed 2 to use tianocore, but all that happens is my Chromebook making a beep and staying at the screen.

I am using a Levano 100e gen 2 AMD (which I think to be fully supported according the device search up tool)

I don’t know if I am missing something or doing something wrong as I checked both Chrultrabook and Mrchromebook websites and did everything that was necessary.
