Is it possible to disable hadronic physics in a given region?

Dear experts,

Is it possible to disable hadronic physics in a given region? (I am not sure if the production threshold are honored by hadronic processes or just EM)

Thank you very much for your time.

Best,
Alvaro

hello,

it is possible but useless - physics will be incorrect. There are limited number of tasks, for which hadronic physics is not needed.
