How to assign fx loop on channels 2&3, not to the channel 1?

[Hellknight]

Hi everyone,
I have put a noise gate and a parametric eq in the fx loop of my mark V, I dont want this to affect my channel 1 soud. My question is: How to assign fx loop on channels 2&3, not to the channel 1?
Thank u if you have a trick or the answer
Ciao tutti, ho meso un noise gate e un eq parametrico nella fx loop del mio Mark 5, non volgio che abbia un effetto sul canale 1. Come fare per mandare l'effetto solo sui canali 2 e 3? Grazie per la rsiposta
Bononjour à tous, j'ai un noise gate et un eq parametrique dans ma boucle d'effet (Mark 5) et j'aimerai activer la boucle d'effet seulement sur les canaux 2 et 3 et pas sur le canal 1, si vous avec une astuce ou la réponse merci beaucoup.

Assuming V90, I don't think this is possible. You can either hard assign it to one channel (back panel) or set to FT SW, in which case you'll have to switch it on/off with the footswitch
