Short description of error
I want to render animation and save specific passes from layers and scenes. I have everything set up in the compositor and i am oupting it to multilayer exr via compositor ouput node. But Blender simultaneously, although i have ouput in compositor, still rendering gargabe frames in format and directory set in Output Properties tab. It cant be dissable, when i put empty path here render just wont start. This make no sense for me becasue it takes space and write disk memory . It just left garbage frames to delete in default /tmp\.
Also, compositor dont save metadata(for example to use cryptomattes in Fusion or Nuke) but Output Properties tab saves.

Exact steps for others to reproduce the error
Just use compositor and set output file node, after clicking "render animation" Blender will save render at the same time to directory in compositor and in Output Properties Tab.
There is no way to save only from compositor output.
