In order to achieve a 0 QBR rating, quarterbacks need to do ALL of these things in a single game:
1. Post a completion percentage of 30.0% or less
2. Average no more than 3.0 yards per attempt
3. Throw for no touchdowns
4. Have an interception/attempt percentage of no lower than 9.5%
In order to score a 0 QBR rating, Quarterbacks need to do all of these things.

Let's take a look at an example of a 0.0 QBR game, which was posted by Atlanta quarterback Josh Rosen on November 14th, 2021.
In the game, Rosen posted this stat line:

14 yards
0 Touchdowns
1 Interception
Rosen posted a completion percentage of 16.6%.
Rosen averaged 2.3 yards per attempt (6 total attempts).
Rosen threw for 0 touchdowns.
Rosen threw for 1 interception.
Add all of that up and you have a 0.0 game.
