Earlier in outliner 3 options were available for each object one of which was disable render. Now only one option is available for each object. Basically how to disable render for single object inside of collection
In the outliner there is a filter option which allows you to enable the Restriction Toggles that aren't displayed by default which includes Disable in Renders (camera icon). Once you have it enabled you can disable any object or collection from being rendered by clicking on the camera icon behind it in the outliner.
Another way is to make this object one hundred per cent transparent.
