[SOLVED] User defined environment variables

Is it possible to have a user define an environment variable in bash, that can be used is subsequent terminal instances to set the verbosity of certain functions using that variable.

Yes it is.

With the condition that the user can enable or disable the environment variable functionality without the need to change their ".bashrc" directly.

When posting homework questions it is expected you show us what have you done already and where you get stuck.

looks like you don't understand it, or I don't understand the question.
You can't modify a shell from another terminal/console/whatever, a running process cannot be altered by setting some environment variables outside (anywhere).
But you can export variables which will be inherited by the child processes (and therefore will be taken into account) - obviously if they will not be lost or overwritten by something like .bashrc or similar.
