Based on the filename Disable-Dm-Verity-ForceEncrypt-03.04.2020.zip, this is a specific tool used in the Android modding community (likely for Samsung devices or similar) to disable Android's security checks.
Evolution: Modern Android (13/14/15) uses Virtual A/B and VABC. The old "forceencrypt" flag is obsolete—encryption is now mandatory and handled differently.
SafetyNet & Play Integrity: Bypassing DM-Verity today breaks device attestation immediately. Banking apps and Google Pay would refuse to run.
The Source: The original maintainer (often credited to Zackptg5 on XDA) has moved on to Magisk modules and multidisabler scripts.
