Fixating on front door

Our front door is right infront of the couch in the living room. Bella my senior min pin is starting to fixate on the door until my bf comes home from work so from 4-6pm she will become super sound reactive and stare at the door.

Sometimes she’ll just bark for no reason staring at the door.

Does anyone have any tips? I can’t take her to the back of the house because she hates being there. I also want to try and help her get past it so we can continue to sit in the living from between 4-6.
