auto generated prefs

[provide a description of the issue]
Every time command Java: Update Project is called few prefs are added by default to

• org.eclipse.jdt.apt.core.prefs:
  org.eclipse.jdt.apt.genTestSrcDir=target/generated-test-sources/test-annotations
• org.eclipse.jdt.core.prefs
  org.eclipse.jdt.core.compiler.problem.enablePreviewFeatures=disabled
  org.eclipse.jdt.core.compiler.problem.reportPreviewFeatures=ignore
  org.eclipse.jdt.core.compiler.release=disable

Is it possible to disable this? In current repository that I am working on I can't modify those files, so I would like to keep them without modification or at least change path where I can specifically update and gitignore them.
I tried copping them to .vscode/ folder with no luck. New option java.settings.url to point custom pref settings with those options also didn’t work.

Any adviced what I could try or what I did wrong?

Environment

• Operating System:
• JDK version: JDK 11.0.1 or OpenJDK-15.0.2 (same behavior)
• Visual Studio Code version: 1.55.2
• Java extension version: 0.77.0

Steps To Reproduce

1. Files org.eclipse.jdt.apt.core.prefs and org.eclipse.jdt.core.prefs have no mentioned options
2. Run command Java: Update Project
3. Files org.eclipse.jdt.apt.core.prefs and org.eclipse.jdt.core.prefs were automatically updated

Review the Java: Update Project command and how it updates org.eclipse.jdt.apt.core.prefs and org.eclipse.jdt.core.prefs. Reproduce with the listed JDK, VS Code, and extension versions, then determine whether these preference changes can be disabled or redirected without modifying repository files; done means unwanted changes no longer occur or a supported setting is documented.
