Current64 - kernel config - CONFIG_HAVE_{GZIP,BZIP2,LZMA,XZ,LZ0,LZ4,ZSTD}

Current64 - In /boot/config-5.10.2-generic I see:
Code:# General setup
.....
CONFIG_HAVE_KERNEL_GZIP=y
CONFIG_HAVE_KERNEL_BZIP2=y
CONFIG_HAVE_KERNEL_LZMA=y
CONFIG_HAVE_KERNEL_XZ=y
CONFIG_HAVE_KERNEL_LZO=y
CONFIG_HAVE_KERNEL_LZ4=y
CONFIG_HAVE_KERNEL_ZSTD=y
.....FAFAIK menuconfig, nor xconfig or gconfig can find these entries, let alone change them.
Any comment will be appreciated.
