If unfortunately you do not have USB debugging enabled you can boot using the Safe Mode key combo to cause Magisk to create an empty file named 'disable' in modules directories which disables modules when next booted with Magisk. Most modern Android devices support such a special key combo at boot to enter system Safe Mode as an emergency option, but **please note** that Magisk's key combo detection occurs _earlier_ than system detection so the key combo timing indicated by many online guides may need to be altered to activate Magisk's Safe Mode. (It's possible to activate system Safe Mode but not Magisk Safe Mode and vice versa.)

The following details should ensure that modules are properly disabled:

1) Many online guides for entering Safe Mode say 'When the animated logo appears, press and hold the volume down button until the system boots' or similar. This may actually be _too late_ for Magisk detection however and result in activating system Safe Mode but modules are not disabled.

2) By pressing the volume down button some seconds before the animation and releasing it as soon as the boot animation appears, Magisk's Safe Mode should be activated without activating system Safe Mode (thus avoiding disabling other device and app settings) and the device should then simply boot to normal system with modules disabled.

3) By pressing the volume down button some seconds before the animation and holding it until the system boots, both Magisk's Safe Mode and system Safe Mode should be activated. Next, after booting back to normal system, modules will be disabled.
