Bode Plot: How to receive always a response from the function even when the function is not defined?

Hello,

We see that in the case of the function Test1 Arg(Test1) cuts -180deg line, as a result, we can have values ​​for:

But in the case of the function Test2 Arg(Test2) does not cut -180deg line, and this means that:

or

or

But I get the red color:

The idea is that I don't want to see this red color (although I know from where this no answer/red color comes -> because the graph does not cut -180deg line), but instead, I want to receive as answer one of the 3 options listed above. Is this possible?

Thank you.
