*As(stated*, the answer involves the offspring of the mating of a rhinoceros
and an elephand.

=GUESSING= that you mean a shell 'envionment variable', the answer is 'yes'.
_How_ one can do it depends on the shell (*unspecified*!) being used.
'unsetenv' _may_ do the trick.  Alternatively a variable assignment with
no value (.e.g "VARIABLE=") may work.
