Thunderbird identities - Is it possible to set "do not reply from this address"?

I am having issues when using identities in thunderbird. I had to set a an identity to one of my aliases to be able to call it from the thunderbird cli (using it for automatic mail composition).
Without the identity CLI does not recognize its address, but now when I reply to any mail sent by me with the alias in CC thunderbird automatically uses the alias identity. (Yes, I am replying to myself using the "reply all").

Is it possible to prevent thunderbird from using the second identity at all?

I already tried:

• Setting random things in "Reply from this identity when delivery headers match" - did not help.

• Main mail is set as a default.
