Skip Big Sur Accessibility screen

Well, I took a look what those other CPs are actually doing which looks to be manipulating the com.apple.SetupAssistant.managed preference domain value. Not seeing anything in Apple's documentation about the new Accessibility pane - https://developer.apple.com/documentation/devicemanagement/setupassistant

Check the PreStage Enrollment pane for this option.

I did a quick test of skipping this option in pre-stage enrollment (Automated Enrollment Enabled). It does indeed to do what I'm looking for when doing an in-place macOS update.

Quite surprising actually. I was probably too quick to assume pre-stage enrollment configuration only impact user experience during initial enrollment.

Thanks @a.feliciano!

I just took a look at com.apple.SetupAssistant on my upgraded machine and saw a key for DidSeeAccessibility

Nice find!

I have a similar problem on jamf Pro 10.25.1 and pre-exisitng prestage enrolments.
Even though I have the accessibility button now ticked, it still displays for Big Sur device enrolments. (Not an upgrade, this is a disk wipe & clean install from bootable USB.)

It could be because the prestage enrolments were already created on an earlier version of Jamf.
I hope I don't have to recreate them from scratch. I will have to test it with a new PSE and see...

Same here, Accessibility is still showing up in DEP process even if this option is checked

There is no option to suppress the Accessibility screen on Big Sur during DEP/ADE because it's presented before the Mac ever communicates with the MDM server.

I have this in a Configuration Profile and it worked to skip it in Big Sur/M1 -
