In my recollection there has been no option to anything with a command receiver at all in past satellites. This receiver was ON to be able to do its function regardless of other 'activities' on the satellite. In other words, it could not be messed with for any reason. Such a capability is absolutely essential for the health (and recovery) of the satellite and its mission.

Please don't assume that it's ok to have the power to a command receiver switchable without substantial discussion and review. All prior AMSAT projects that I'm aware of have had command receivers always on, even if they weren't always in use. I'm pretty confident that includes both of a redundant pair. Happy to be corrected by others with better knowledge of history if I'm mis-remembering some relevant case.
