How to disable diagnostics on specific lua files?

[linrongbin16]

I have a file lua/commons/_system.lua and I want to exclude it from the .luarc.json file, I found there's an option diagnostics.disableScheme, I set it to:

{
  "diagnostics.disableScheme": ["lua/commons/_system.lua"]
}

But it's not working for me. How should I do?
