Hi,
If you need to achieve it from studio, you can do as follows:

* activate developer mode
* create a new user group, from settings -> users & companies -> groups
* name the group as, "show cost price", and export the created record. ( to generate external id for record)
* now open the form where you need to hide the cost
* enable studio and click the field and assign this group to this field

Thanks
