Hide buying price and margin

Dear All,

I hope all of you are doing well. Actually, I would like to hide the buying price from the product cart. I have few employees that access my Dolibarr e.g. warehouse department and sales force. I do not them to see the buying price.
Any advice in this regards.

Regards,
Tuhafi
