Is there a way to block the flexible update flow monits?

There are apps I don't want to update for some reason, like missing features, new unwanted features, or tons of video ads with newer versions. Often when I launch some apps, I get the monit asking me to update such an app. As I found out, it's so called "flexible update flow " that came with Android 5.0 (API v21). Is there a way to block it without patching such an app? Like blocking some Google service/app drawing on top?
