Do you mean you want the ability to turn it on regardless of key position?
If so simply switch the fuse tap to a fuse that is permanently on.
Unless you're talking about an independent switch to activate the switch pod when the key is off. Or basically all switches become active when a key is in the ignition or a separate master switch is on.
If you want to do that, the easiest way would be to tap into the turn-on wire with a diode (like the ones used for trailer wiring). The one ended (cathode) side goes to the switch panel, the 1st upstream (anode) side goes to the ACC trigger wire you already have, and the 2nd anode goes to a switch and then to a permanently on 12V source.
In that case the fuse panel would become active if the key is in the ignition and turned, or the switch is turned on, or both. You need the diode to prevent backfeeding the ignition source.
I'm assuming there is already an internal relay for the lights or any other fuse panel accessories. You wouldn't want to tap any significant power out of an existing accessory wire.
This is the type of diode I am referring to:
