Can the effects loop be set permanently on, allowing the Boost to be toggled separately?

Yes, the Radial Engineering PZ-Pre effects loop can be set permanently on using the recessed LOOP ON switch. When this switch is pushed in, the effects loop remains on all the time, and the BOOST footswitch is then dedicated to toggling the power boost function separately.
