I have explored and Found solution to display the blank rows in the Matrix visual ( i.e. display the rows which has no values)
Refer the below post i submitted for more details (https://community.powerbi.com/t5/Desktop/Need-help-on-designing-Visual/m-p/561243#M264742)
Rows --> select the Row field and right click and choose "Show items with no data" option.
Same applies to,
Columns --> select the Column field and right click and choose "Show items with no data" option.
Refer the below working visual:
Item5 has blank values but still the entire Item5 Row is displayed in the Matrix visual.
