This measure was taken as a sign of support for the actor after he was injured while clearing snow.

Streaming service Paramount+ removed the wounds on the face of Jeremy Renner’s character on the Mayor of Kingstown poster in support of the actor after he was injured while shoveling snow. The Hollywood Reporter writes about it.
In addition, series creators Hugh Dillon and Taylor Sheridan have come up with ideas for a third season, which will begin production if Jeremy Renner is ready to return to filming.
What happened:
The incident occurred on January 1 after a snow storm that hit the state of Nevada. Renner planned to clear the snow from the road next to the house with his personal snowmobile. While clearing snow, the actor got out of the cabin of the snowmobile to talk to his relative, and the car rolled forward. Renner tried to jump back to stop the car, but was hit by the wheels. The snowplow weighing over 14,000 feet kept going until it crashed into a pile of snow.
