Same applies to all other stuff, that's using optionOnOff:
rf69_set_sync_enable(optionOn/Off) enables and disbales sync,
rf69_set_crc_enable(optionOn/Off) enables and disables crc,
...

In my opinion, if we want perfect clarity, we should stay with optionOnOff.
If we are ok, if rf69_set_sync_enable(false) disables sync,
in my opinion, we also have to be ok, if rf69_set_amp_X_enable(false) 
disables the amp.

Cheers,
Marcus
