We did not use any post discharge treatment. It went from the bombardment to the coating stage directly through a light trap to prevent UV fogging the film or paper.
Any preventative measures were in the emulsion.
BTW, if you cross process Endura you will see a tiny amount of mottle that is caused by the "incorrect" process of Endura to a reversal image. The Yost-Heidke method was engineered in Endura for neg-neg processes. It is different for pos-pos processes.
