Install certificate for HTTPs without setting password on an unrooted Android -

here problem:

i want import root ca https on android device, android system asks me set password/pin. after password/pin setted, ci test cases have unlock screen , input password/pin, difficult implement. not have idea part of work. so, want ask if there way install root ca https on android devices.

ps, have tried on google, find have root devices, least thing want do.

any ideas or solutions welcomed.

for test/debug builds can include certificate app accepted trusted root certificate: using custom certificate trust store on android

there ways automate pin/password entry: how unlock android phone through adb

another alternative in situation may apps keep device active , therefore prevent device enter locked state.
