Ambient oclusion in the RTX option

Hello

is there a way to render with ambient oclusion in v-ray 5 for rhino 7 in the RTX option?
it can be a plugin.

is it possible to render only the ambient occlusion in the CPU option and then insert, via photoshop, in the image rendered with the RTX option?

thanks

An AO render pass can be done per Extra Texture channel and dirt shader. For example here it was mentioned:

this scheme that you suggested: Extra Texture channel and dirt shader, is it possible to be applied directly to the render with RTX?
or is it necessary to use photoshop to insert?

I got it

A common use for the ExtraTex is to use [Dirt] as the texture, which creates an ambient occlusion element for use in the composite.

Extra Texture - V-Ray 5 for Rhino - Chaos Help (chaosgroup.com)

is in the manual:

A common use for the ExtraTex is to use [Dirt] as the texture, which creates an ambient occlusion element for use in the composite. In this way, ambient occlusion can be controlled separately during the compositing process.

is it possible to make the composite on the own v-ray for rhino 7?
or do i have to use photoshop?
