I haven't found any way to unset environment variables in profiles and conan recipes.
Tools module has
environment_append, but it can only add or replace something, not delete. Empty value is not the same as unbound variable, soenvironment_append({"VAR": ""})does not work in some cases.environment_appendcould acceptNonevalues in a dictionary and unset the corresponding variables for them.For profiles I have no idea yet.
