Identify duplicate values at first column in csv file

Input
Code:
1,ABCD,no 
2,system,yes 
3,ABCD,yes 
4,XYZ,no 
5,XYZ,yes
6,pc,no

Code used to find duplicate with regard to 2nd column
Code:
awk 'NR == 1 {p=$2; next} p == $2 { print "Line" NR "$2 is duplicated"} {p=$2}' FS="," ./input.csv

Now is there a wise way to de-duplicate the entire line (remove the duplicate) based on the criteria found within this one liner or wrapped around additional logic?
