My understanding, which is very limited, is that any updates or changes are applied directly from the dealership. The only -- over the air updates -- that I am aware of pertains to the navigations system. The infotainment system is indeed a weak link for Honda reliability.
"Over-The-Air" System Updates for Passport - How often do they come out? Current System Versions?

The infotainment system stores specific failure or shutdown events that can be accessed via the Dealer Diagnostics Menu, however, it does not store all error events and the error messages store are not very descriptive so if your intention of entering the diagnostics menu is to narrow down what needs to be fixed so you can carry out the repair then you are not in luck, only the dealer tech have specific instructions on what to do about specific error messages.
A sample of the message is below. 👇
The infotainment (crackling/popping) issue plaguing the Passport is limited to the 2019-2021 model years, a few 2022/23 owners have reported infotainment issues but those are rare and I don't believe they are identical to the catastrophic failures in the 2019-2021 years. Honda has several fixes for the 2019-2021 infotainment problems but the fixes are complex to conduct, it may involve taking apart the dash or gutting out the entire vehicle if the floor harness has to be replaced. A successful rectification depends on the technical expertise and experience at the dealer you take your car to carry out a fix. Some owners do the fix just once and the issue never returns but some find that they have to return as many as four times before they get a successful and permanent fix.

Honda generally does not update individual systems like cameras, LKAS, RDM, ACC etc. unless there is a major event that demands an update, all these systems work with the software that was installed at the factory. The recent update to the Idle Stop system is due to a safety investigation by the NHTSA which helped Honda come to the realization that the battery and the starter are being subjected to loads of pressure. And the also recent update to the TCU (Telematics Control Unit) was due to the fact that Honda installed a 3G modem in it and US phone networks were shutting down their 3G networks. If you recently purchased a pre-2022 Passport you should check to confirm that the previous owner carried out the update, if the update was not done before it expired then you meed a completely new TCU if you wish to use any of your Passport's inbuilt communication functions.

Agree with Hubb's post above, my Passport is also auto-connects to our home wifi. The only update that my 2020 Passport downloaded and installed (that I am aware of) was in January, 2022, an OTA Update for TSB 22-001.
There have been previous OTA updates, see posts below:

Got the notification (ding and "1" displayed on top line) yesterday that update was available. Performed it. Says 40 mins., but don't think it took that long. Long list of fixes you can view here. https://owners.honda.com/Documentum/ota/2019_Passport.pdf SOFTWARE VERSION B.1.3.4 SOFTWARE VERSION...

I will have to figure out what this TCU is and what is does. And actually no idea if it was updated. My iPhone connects just fine and I was able to place a call via the connected iPhone. But again will have to read up on it
Such a disappointment that there was only one over the air update in so long.
I will have to find a spare USB. To play with that usb.Honda.com update website.
Lots more to read.
.Thanks for the PDF link. I already downloaded the pdf to the computer because it’s just easier to index and find info!
have a blessed day!

As I said I read about it (on the internet) and you know you can believe everything you read on the internet.
There is also a "rumor" or a "rumor of a possibility" that if you stop making payments on your Tesla, it will use the "self driving" feature to leave your driveway in the middle of the night, or leave you stranded while out in town. and return to "killer Tesla base" but that is not happening either.... but its possible, and at that time "subscriptions" are the least of our worries. =)As I said I read about it (on the internet) and you know you can believe everything you read on the internet.
