Huge qty buying anonymously

How do HNIs and Ultra HNIs avoid limelight from their large one day accumulation of stocks?

let’s assume if an HNI wants to buy 20 crores of Reliance Industries @ 1232 i.e approx 162337 shares how does he protect himself from being in the limelight?

Let’s say if the trade is completed through 160 orders of 1000 shares each.

Is there any possibility of his trades being covered in any of the EOD reports of NSE?
