My ISP is injecting ADS in everything that can connect to the internet (browser capable, like Steam client) through an advertising site.

I want to block all incoming connections through a domain my ISP is using to inject these ADS, how do I do that?

If you know the domain or IP addresses you can use the blocked network zones feature to block access for all applications.
