Disable chromium boot up PYNQ2.5 for Ultra96-V2

Hello! I am new to the FPGA community and I’ve downloaded a PYNQ 2.5 image onto my Ultra96-V2 board for a period of time now but I’m still not sure how to get around the desktop environment quite proper. I was wondering if its possible to turn off the chromium that starts on boot up or maybe change the wallpaper of the desktop even?

Thanks for any kind assistance!
