If want to remove Qt completely from the build, use the following command, which builds an i.MX image with a GUI without Qt content:
bitbake imx-image-multimedia
Additionally, please ensure that you perform a clean build or start from a fresh build directory to ensure a clean build environment.
To clean and rebuild a specific package, use:
bitbake -c cleanall <package_name>
bitbake <package_name>
