I'd like to inform you that we've created a guide, what needs to be set via MDM (like JAMF) in order to pre-approve all system accesses.
If the system access are pre-approved and ESET Endpoint Security product for macOS is installed there will be no system notification shown to the end-user = silent installation. 

You can find a guide here: https://help.eset.com/ees_mac/6.10/en-US/install_remote.html

From now you can find instructions on how to pre-approve: 

• System extensions (old)
• Full Disk Access (updated)
• Firewall (updated)
• Web Access Protection (new)

Please note, that having MDM is mandatory in order to pre-approve all required system accesses. It can be any MDM compatible with macOS. 

Please note, that this guide can be used with any version of ESET Endpoint for macOS applications (no updated version is necessary).
