To disable a single patch file, you can do one of two things:
Option1: Navigate to the patch file in the file system, and rename it to end in something other than .config. For example, rename Sitecore.Analytics.Config to Sitecore.Analytics.Config.Disabled
.
Option2: Add the patch file to a <loadOrder> section and add the
mode="Off"` attribute.
For example:
<add path="Sitecore.Analytics.Config" type="File" mode="Off" />
Note: Option 2 will only work with 9.0 or later versions.
