Until a more elegant solution is found you can set the APM value like this:

camcontrol cmd ada0 -a "EF 05 00 00 00 00 00 00 00 00 F3 00"

EF is setfeature command
05 enables APM feature
F3 is 243

To disable APM you can use:

camcontrol cmd ada0 -a "EF 85 00 00 00 00 00 00 00 00 00 00"

You can check the value with:

camcontrol identify ada0
