Disable SharePoint Online Declarative Workflows

Question

I am trying to set the following SharePoint Online site properties to $false, but keep receiving "Access Denied"
AllowCreateDeclarativeWorkflow
AllowSaveDeclarativeWorkflowAsTemplate
AllowSavePublishDeclarativeWorkflow

I tried PNP

$Site = Get-PnPSite
$Site.AllowCreateDeclarativeWorkflow = $false
$Site.Context.ExecuteQuery()

and CSOM

I am running with AppId and Secret with full control permissions over entire tenant. I also tried using credentials of site collection administrator.
Custom scripts are disabled on tenant level.

Could reproduce on multiple sites and another tenant.

Would appreciate any hints.

@Ana ,

Same result with you, workflow has been deprecated in SharePoint online, not necessary to disable it for yourself, for more information ,please refer to https://support.microsoft.com/en-us/office/sharepoint-2010-workflow-retirement-1ca3fff8-9985-410a-85aa-8120f626965f

These settings manipulate SharePoint 2010 workflow availability which has already been removed from SPO, i.e. the properties won't do anything.
