Helllo. Thanks for help.

Yeah. I read this article.

My scene have correct albedo (no red albedo).  ( This noise appers in material override with correct albedo - white albedo -  )

Its noise dont provide from material (because all scene have override material)

I have only 4 lights in scene...  and i have noise in indeirect light and direct light :(

Are you using portals in this scene? Be sure to use them: https://coronarenderer.freshdesk.com/support/solutions/articles/5000501660
You can also try increasing GIvsAA to 32, and leaving LSM at the default of 2. This should give you better GI quality at lower amount of passes, and in a shorter time.
You can also lower MSI (https://coronarenderer.freshdesk.com/support/solutions/articles/5000515636) to 10, but it will most likely affect the lighting in your scene.
