exposing just certain parameters on prefab

From what I can see prefab instance still seems to expose all the children and their parameters for editing (overriding), which however powerful, it can be very messy and difficult to work with, also dangerous as any artist can change anything

Maybe I'm misunderstanding purpose of prefabs and this would be a different type of instanteable game asset type, but essentially I'd like a way to create a prefab that has only a few specific parameters of my choice exposed from all the possible parameters on all it's children
so that each instance of such "prefab" in the editor shows only those parameters, doesn't allow to expand the hierarchy or even see/override the actual children or children's parameters, just the chosen, exposed ones directly on the prefab
(like Houdini's HDA, Unreal's Actor, ...)

in a similar way as I can create properties in Shader Graph and only those show up as parameters in the inspector for my shader

this would make it more straightforward to have specialised prefabs that artists will be able to tweak easily but only in a way it is intended, without requiring artists to hunt through the hierarchy for secific parms or even have that freedom and therefore potentially override something they are not supposed to touch

is such thing possible? Preferably without custom scripting, just like mentioned shader graph feature or the other mentioned softwares

 

See FAQ item "Can we get the ability to treat Prefabs as “black boxes” where specific properties can be set as exposed and only those can be edited at all on Prefab instances?"

thanks for the link, the answer makes sense, hopefully you'll find a good solution
even if it's just defining custom UI properties for the blackboxed prefab and internally linking them to the actual properties with 1-1 connection or some custom relationship
