How to hide formula in libreoffice calc?

Question

libreoffice

You need to make a price list in LibreOffice Calc with the ability to hide calculations. I need to be able to change the rate and markup for different users without them seeing the calculations. The most obvious thing I see is saving to pdf, but I'm afraid this will complicate the work of clients. I hid the columns with the initial price and rate, but when you see the formula, you can see that they are hidden and see. Are there other solutions???
