Default Heads-up notifications

Is there an easy way to enable this with out the xposed module? Here is what I'm talking about for anyone that hasn't seen yet: https://android.googlesource.com/pla...base/+/157026f .......it has an adb command to enable but I'm also wondering if that is for a computer and if I can issue the same command from the android terminal. Thanks in advance for any help
