@rama

Have you explored the following option:

1. installing the sysfsutils package:

  sudo apt install sysfsutils

2. Then append a line with that setting to /etc/sysfs.conf:

  kernel/mm/transparent_hugepage/enabled = never

Also please check the following as well:

cat /sys/kernel/mm/transparent_hugepage/enabled 
  #  always madvise [never]
cat /sys/kernel/mm/transparent_hugepage/defrag
  #  [always] madvise never
cat  /proc/cmdline
  # initrd=\initramfs-linux.img root=/dev/sda2    rw splash transparent_hugepage=never
