Disabling screen-on/wake-up reaction to change in power status?



I've noticed that my rooted XT1527 2nd Gen MotoE will automatically "wake up"/turn it's screen on whenever it recognizes that it has been given a power source (or the power source has been taken away).

Basically, every time I plug in, or unplug the power cord, the phone's screen flicks on in recognition of the change in power status. I want to disable this and have the phone screen only turn on if I physically press the power button.

The reason I'm asking is because I am experimenting with charging my phones with solar panels. Things work great when it's very sunny out, but when it's cloudy, even though the phone stays plugged to the solar panel, the charging source flickers in and out with the clouds (which seems to be the equivalent of plugging and unplugging the phone from the commercial charger in rapid succession). When this happens, the phone's screen turns on in recognition of either gaining or losing the power source, and on cloudy or rainy days, this process that happen so consistently that the phone screen essentially stays on all day and slowly drains itself of battery much more quickly than it would have if it didn't feel the need to turn on the screen every time the power source came back or went away.

Any suggestions for how to disable this "screen on to recognize change in power status" feature?

My phones are rooted and I've made some simple firmware modifications to them, but I'm definitely a n00b.

I won't go into the details, but I'm using the phones for scientific research, which is the reason for the solar panels. I want my phones to be able to stay on and collect data, but I don't want that screen waking up and flicking on every time there's a change in power status! I'd love to be able to get rid of this feature! Any ideas?
