How to delete or disable Device Security on Samsung S6/7 running Android 7.0?

[Android Central Question]

I'm not sure if this is possible, but I'm trying to test my phone with a customized security software but I need to delete Device Security to test it out. Any ideas on how to delete/disable Device Security? I'm okay if it requires deleting Device Maintenance.

I've rooted my device and have tried disabling/deleting device security and device maintenance but when I do so, it crashes the phone so that I have to factory reset it. Any suggestions?

Evidently Device Security has something in it that the phone needs to run, so you'd have to disassemble it, find out what that is, then write it as a stand-alone app.
