Can we obtain non-lorentzianLorentzian metric from lorentzianLorentzian metric, through renormalization methods?

Since low-energy, non-relativistic thermal field theories are defined in Euclidean spacetime, while high-energy relativisticerelativistic theories are define in Minkowski spacetime, I was wondering if there are renormalization methods that can show such a change in metric signature.
