[Consider a scenario](https://en.wikipedia.org/wiki/Kazakhstan_man-in-the-middle_attack) where my ISP attempts to use a Man-in-the-Middle attack against me to read and possibly modify my Internet traffic. 

What can I do to access the Internet and still ensure the integrity and confidentiality of my traffic?

Furthermore, are there techniques I can employ to make it more difficult for the ISP to notice that I am trying to evade their Man-in-the-Middle attack?

Additional context from the comments: The ISP doesn't install a cert on my PC. Rather, I get a warning, and my only options are either to: A) skip the warning and let the ISP Man-in-the-Middle me; or B) stop using the Internet.
