I'm about to leave on a 3 month trip overseas. I intend to leave my Passport in the Driveway in San Francisco.
Do I need to disconnect the Battery or something? Or can I just park and lock it?

The battery will be dead by the time you return if you leave it in the vehicle, also considering the type/quality of OEM battery used by Honda you might also not be able to recover any usefulness out of it if it's a few years old and you let it completely drain.

If you have some indoor hardware space I suggest disconnecting the battery and connecting it to a trickle charger indoors. I'm presently on an overseas trip myself so I have my wife "warm up" my 1999 Accord and my 2008 Pilot for 30 minutes once a week, but that will not be sufficient for the Passport so we usually put her own 2020 Passport Touring on a trickle charger when it's not being driven.

Will you be able to park it near a 110v outlet? If so get an AGM trickle charger LINK and make sure the sun roof is closed.

We don't drive our Passport in the winter...We park it from Dec. 1 till April 1 in our heated garage...We stabilize the gas and put it on a battery maintainer...Also cancel the Sirius radio...Our insurance company puts the vehicle in "lay up status"...Its insured but no liability or collision...Fire & theft only...Saves a little $$$...

We now exclusively drive the Ridgeline with the studded winter tires during the winter months...larryd

I would disconnect the battery unless you have a battery tender.
Clean the car inside and out.
Fill the tank all the way up.

I use to store my 2007 Mini for 3 to 4 months. I just disconnected the battery and it started up no problem.

Get yourself a cheap solar trickle charger/maintainer and leave it plugged in. Wake sure it faces South.

You bought a 40K vehicle, why not pop for short term storage in a covered, secured facility. You could go with a simple storage unit or you could go with one of the many car storage companies in the area that will start the vehicle, move it around a bit to keep from flat spotting the tires. This way you have no worries about it being out in the oh so predictable California weather and with an average of 74 burglaries to vehicle a day in SF, you are less likely to come home to a vehicle with a missing window at the least, and missing components/property or more.
