IIRC the IQ Cyo uses european 3mm spade connectors for hookup. Not really designed for frequent disconnection and reconnection.

Setting up something like the OP wants to do depends on your mechanical abilities and access to equipment. I just made up a quick release bracket for mounting my new Light On! dynamo headlight to my handlebars. I prefer a hard mount rather than the standard Light On! O ring handlebar mount for a headlight so adapted the mounting bracket set from Cygolite headlights to the Light On! headlight. It required making up a 1.5" by 2" by 3/8" thick aluminum plate and then accurately drilling and tapping 4 holes in the plate. The headlight will come off the bike in a few seconds and reinstall without having to mess with beam adjustments.

The original Light On! handlebar mount is quick release but uses an O ring to hold the headlight to the handlebars. IMO too easy to knock out of adjustment and headlight removal and reinstallation requires readjustment of where the beam points after every installation.

The Light On! standard wiring from the dynamo to the headlight also has a single quick disconnect plug at the headlight connector.
