I use macrium reflect and i can do what you are saying because i already have a vanilla backup with no security software. I just feel mad about being ignored so i don't want to have anything to do with Adguard.Trying without EAM & Rehips would have let us know if there is any incompatibility prob on your system.
Anyway, uBlock Origin it is...excellent software.
By the way, why dont you try software like Rollback Rx?
Its handy for the above & other scenario...create restore point, uninstall EAM/Rehips, test with Adguard, after test restore back to created restore point, any previous restore point.
It has its quirks But you are an expert & can use it efficiently.
