Warning: No swap limit support in Docker when installed using diskbot

Question

I have created custom OS (Ubuntu 20.04) using diskbot with LVM partition (OS (50GB) and SWAP (4GB)) During the vmdk setup I am Upgrading OS and then installing docker into vmdk.

docker --version
Docker version 24.0.5, build ced0996

root@ub20:~# free -hm
              total        used        free      shared  buff/cache   available
Mem:          3.8Gi       875Mi       367Mi        30Mi       2.6Gi       2.7Gi
Swap:         255Mi       0.0Ki       255Mi

My /etc/fstab file content

# This file is autogenerated
# <filesystem>  <mnt>   <type>  <opts>  <dump>  <pass>
LABEL=GRUB_CFG  /grub   ext4    defaults,errors=remount-ro  0   1
LABEL=OS        /       ext4    defaults,errors=remount-ro  0   1
LABEL=SWAP      none    swap    sw                          0   0

Now when I boot up the VMDK using virtual box (Version 7.0.8 r156879 (Qt5.15.2)) and run "docker info" command I am receiving warning "Warning: No swap limit support"

I have tried editing grub file etc/default/grub

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

then reboot the machine

Ref : Docker -- WARNING: No swap limit support

But I am still getting same warning.
