Page Layout and Site Template Settings - Properties using PowerShell

Question

I have a requirement where I need to access the Site Templates and Page Layouts and the Default Page layout. I'm able to access all the properties using

$web.AllProperties["__WebTemplates"]
$web.AllProperties["__PageLayouts"]
$web.AllProperties["__DefaultPageLayout"]

I was able to update all the 3 properties. But I'm unable to update the Reset all subsites to inherit these preferred subsite template settings and Reset all subsites to inherit these preferred page layout settings.

Can anyone help me with the properties of the above? I need to make the checkbox checked true using PowerShell.

Do it via the UI and then inspect how the web properties have changed. My guess is, they disappear altogether. So, remove the web properties.
