Hardened aggressive mode?

On my Avast free edition General > Enabled Hardened mode > Set to aggressive.

Was running Dell Diagnostics had exclude, to allow some test to run.

My question is would those changes in settings be stored in Avast, if yes how do I clear them?

Thanks.

They’re stored, they can be changed if you go to settings, scroll down to ‘exclusions’ and selecting the hardened mode tab
