You can check which kernel you are using with 'uname -r'.
Here you can see that my Pi 2B is using the v7 kernel.Here you can see that I've got the v6, v7, v7l and v8 images installed.v6 is for Pi 1 and Zero, v7 is for Pi Zero 2W, 2, 3 and 4 in 32-bit mode, v7l is for Pi 4 with 4GB or more of memory, v8 is for Pi Zero 2W, later Pi 2, Pi 3, 4 and 5 with 64-bit mode support.
So for this PI I can safely remove the v6, v7l and v8 imagesI'll leave disabling the initramfs for someone else to answer, but it has been mentioned before and a quick search should fine the required setting.
Here you can see that my Pi 2B is using the v7 kernel.
