Enable modern creation forms for Document sets

Summary

I've found that setting the NewFormClientSideComponentId to NULL on a documents set content type will cause it to render a modern creation form over the default, this script will help you do that. (Also see alternate version below, which works on the Content Type Hub.)

# SharePoint online site url
$siteUrl = Read-Host -Prompt "Enter your site url (e.g https://<tenant>.sharepoint.com/sites/contoso)";

# Connect to SharePoint Online site
Connect-PnPOnline -Url $siteUrl -Interactive

# Get the doclibs on the site
$lists = Get-PnPList | Where-Object {$_.BaseTemplate -eq 101}

# List the document libraries
foreach($list in $lists){
    Write-Host "[$($lists.IndexOf($list)+1)] $($list.Title)"
}

$index = Read-Host -Prompt "Which list to you wish to modernize your content type"

# Get the "Folder" content types on the document library
$cts = Get-PnPContentType -List $($lists[$index-1]) | Where-Object {$_.Id.StringValue.StartsWith("0x0120")}

foreach($ct in $cts){
    Write-Host "[$($cts.IndexOf($ct)+1)] $($ct.name)"
}

$CTindex = Read-Host -Prompt "Which content type to you wish to modernize"

# Null out the NewFormClientSideComponentId as that seems to bring it to modern UI
$cts[$CTindex-1].NewFormClientSideComponentId = $null;
$cts[$CTindex-1].Update($false);

Invoke-PnPQuery

Write-Host -ForegroundColor Green "All done"

This alternate version, based on Dan's script above, works on the Content Type Hub, allowing you to modernize Document Sets stored at the enterprise level. See Modernizing the Document Set NewDocSet Form for more details

$tenant = "YourTenantName"

$cts = Get-PnPContentType | Where-Object { $_.Id.StringValue.StartsWith("0x0120D520") }

foreach ($ct in $cts) {
    $currVal = "❌"
    if($ct.NewFormClientSideComponentId.Length -eq '') {
        $currVal = "✅"
    }
    Write-Host "[$($cts.IndexOf($ct)+1)] $($ct.name) $($currVal)"
