I want to see just unblocked sites in search result

Many many sites are blocked in countries like Iran and China. Some of them blocked by local government and others do not get services by U.S sanction low. Every google search in this countries end in some block sites. Even Ordinary search like how to set my wifi Android phone show results for example of VOA news which is blocked in Iran. So annoying. Does google web search have any option to just show us ONLY non blocked sites according to region? Note that this problem is for a large portion of users for example just China and Iran in total have about 1.5 billions population with many internet users. Useless search result an clicks cause waste of power and time and help to faster global warming
