Ok so it worked for me by looking at:

and

Very helpful links. Although their solutions didn’t directly work for me but made me understand the problem more. I have an eMMc based system too from a 3rd party vendor so this my “no flashing required” solution:

cat /proc/cmdline

copy the contents of the above command and add it in:

vim /boot/extlinux/extlinux.conf

instead of the APPEND that is already there replace it with APPEND and the contents copid instead of ${cbootargs}, that is my file after the edit: NOTE MAKE SURE TO BACKUP extlinux.conf or the Image in /boot just in case.

that might not be the cleanest solution and a better one might be to edit the bootargs in a cleaner way such as in: Jetson nano Boot messages are not hiding - #12 by linuxdev but for my case I thought because its a 3rd party vendor I might do some flashing so I went with the lazy option.
