Naming convention in Kconfig?

[LaWi14]

Hello forum,
I am using options that I set up in my project's Kconfig.projbuild. As all configuration of a project (ESP hardware, IDF, user) ends up in a flat file ("sdkconfig", all prefixed with CONFIG_), how can I avoid a name clash with existing system entries? Are there any naming rules / reserved prefixes for user app usage?

Sorry if this was already answered, but I did not find the response with my web searches.

Thank you in advance.

Not really, unfortunately. If your project name is somewhat unique, you can use that as a prefix (CONFIG_PROJECTNAME_MY_OPTION) and you can be reasonably sure nothing will clash.
