mpfs-dev-cli or core-image-minimal-dev-icicle-kit-es : rootfs.wic generated is 7.3GB

[anjaliigedam]

Followed steps to build rootfs.wic for mpfs-dev-cli or core-image-minimal-dev-icicle-kit-es
https://github.com/polarfire-soc/meta-polarfire-soc-yocto-bsp

Generated rootfs.wic is 7.3GB
#1 I tried to remove the various additional recipes like meta-multimediate/webserver/networking, and yet rootfs.wic is 7.3GB.
How can I reduce it?

#2 I tried to flash this rootfs.wic on the Polarfire icicle-kit and it says it only has 7.2GB of memory.
How can I flash the above?

#3 If I want to use the MUX to switch between SD-card and on-chip emmc, is is external jumper based
or I need to follow some steps listed on the some of the documentation page?
