Hmm, those seem like completely unrelated questions to me. Do they seem
related to you?
Coordination number and sigma2 are highly correlated as both alter the
EXAFS amplitude. That cannot be "broken".
You can set maximum and/or minimum values for parameters in a fit. This is
much more robust in Larch than in Ifeffit, and is documented at
