How can I ignore binary caches when running nix-channel commands?

Quite often, I’m away from home where I have a binary cache set for 192.168.0.6 and I run into errors like so: sudo nix-channel –update unpacking channels… warning: unable to download ‘http://192.168.0.6:8899/nix-cache-info’: Couldn’t connect to server (7); retrying in 305 ms warning: unable to download ‘http://192.168.0.6:8899/nix-cache-info’: Couldn’t connect to server (7); retrying in 693 ms…
