Sharepoint - folder permissions and recycle bin

Question

Hello everyone, I would like to ask some questions. We have several libraries on Sharepoint where unique permissions were set at different directory levels. Is there a way to now bulk end unique permissions on all library levels (on all folders and all subfolders) so that everything completely inherits permissions from the main library? The second question: if I change the permissions on the main library, is there a way to make the permissions also apply to the pads that have disabled inheritance from the parent folder? And the last question, is there a way to turn off the fact that deleted files from Sharepoint will be displayed in the Windows Recycle Bin for all users who had the file synchronized via Onedrive to FileExplorer? We have a problem with this, that the user who did not delete the file can then restore it and it makes a mess on Sharepoint. Thank you very much Josef

1.You could use following PNP PowerShell to delete unique permissions for a document library.

#Set Variables
$SiteURL = "https://tenant.sharepoint.com/sites/marketing/2018"
$FolderURL = "/Shared Documents" #Document Library Site Relative URL
 
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive  #-Credentials (Get-Credential)
 
#Function to reset permissions of all Sub-Folders
Function Reset-SubFolderPermissions($FolderURL)
{
    #Get all sub-folders of the Folder - Exclude system folders
    $SubFolders = Get-PnPFolderItem -FolderSiteRelativeUrl $FolderURL -ItemType Folder | Where {$_.Name -ne "Forms" -and $_.Name -ne "Document"}
 
    #Loop through each sub-folder
    ForEach($SubFolder in $SubFolders)
    {
        $SubFolderURL = $FolderUrl+"/"+$SubFolder.Name
        Write-host -ForegroundColor Green "Processing Folder '$($SubFolder.Name)' at $SubFolderURL"
 
        #Get the Folder Object - with HasUniqueAssignments and ParentList properties
        $Folder = Get-PnPFolder -Url $SubFolderURL -Includes ListItemAllFields.HasUniqueRoleAssignments, ListItemAllFields.ParentList, ListItemAllFields.ID
 
        #Get the List Item of the Folder
        $FolderItem = $Folder.ListItemAllFields
 
        #Check if the Folder has unique permissions
        If($FolderItem.HasUniqueRoleAssignments)
        {
            #Reset permission inheritance
            Set-PnPListItemPermission -List $FolderItem.ParentList -Identity $FolderItem.ID -InheritPermissions
            Write-host "`tUnique Permissions are removed from the Folder!"
        }
 
        #Call the function recursively
        Reset-SubFolderPermissions $SubFolderURL
    }
}
   
#Call the function
Reset-SubFolderPermissions $FolderURL

2.If the child folder does not have permission inheritance from its parent folder, there is no option to apply the permission change for the parent folder to the child folder. The only way is you need to manually change permission for the child folder.

3.It is decided by Windows that deleted files will be move to Windows recycle bin. It cannot be disabled by SharePoint.
