Sound mods in Squadron realistic battles

Recently started using RCSM but had someone tell me using it in Squadron battles is bannable so I removed it for the SRB matches. Reinstalled after SRB. Just want to know for sure if it is a bannable offense or not so I can save myself the effort of installing/uninstalling every time.

as I am aware there are no special rules for SRB.
So use them as you wish.
Also people just can use ULQ settings etc and have a massive advantage over the players, playing on ultra, with grass enabled everywhere etc
