Right, i.e. --fixed-size 4G or --size 4G

see https://docs.yoctoproject.org/ref-manual/kickstart.html

And you want to not install expand-on-first-boot in that case, or add
another last partition to become the subject of growing.

That whole on first boot growing is meant for cases where one does not
know how big the storage medium is going to be and use all of it. If
you know how big it is going to be, or if you do not need the space ...
it is likely better to avoid such dynamic resizing.
