How to undo inheritance in web.config?

Question

ASP.NET

There are two very crooked applications on web.config.
One in the root wwwroot, the second in a subfolder.
The problem is that the one in the subfolder stubbornly does not work, while the one in which the web.config is active at the root. It is worth renaming it (so that it does not work) as it starts working.
I tried adding the line to the root

<location path="." inheritInChildApplications="false">

did not help.
Interested in any of the dirtiest hack how the whole thing can be run.
