SharePoint Page Section Collapsible

[kymcha]

I have a SharePoint Online page section that has the "Make this section collapsible" set to Off. I'm using PnP PowerShell Set-PnpPageTextPart to update the text in that section and that works fine BUT the "Make this section collapsible" gets changed to On.

If I do a Get-PnPPageComponent and inspect the Section property, I can see that there is a Collapsible: True property but I can't figure out how to set that property to False. Any ideas?
