How to reduce build repo size for full image

[mahesh93]

Hi,

using below commands:

$ DISTRO=fsl-imx-xwayland MACHINE=imx8qxpmek source imx-setup-release.sh -b build-xwayland
$ bitbake imx-image-full

   build repo size is huge 250GB+ and there are 9000+ tasks, i dnt have space in machine, is there any way so that we can reduce repo size ? something like disabling backend...I want it to enable eIQ features on imx qxpmek B0.
