Disable FirstName and LastName of customer

I need to disable FirstName and LastName fields everywhere in my store (Registration, Profile, Contact Forms).

Is there a good way to do that with no customization?


Currently a just renamed them but this is not what I want.


Of course I could create a plugin for that.
Or make those fields hidden in my theme with predefined values.

Hello,

I am not sure but i thing this is out of box.

You have to do customize to achieve this.

If you found any solution without customization than please post here.

Hope you will understand..!!
