Disable SharePoint Social Bar

myansona You can do it using either SharePoint Online PowerShell or PnP PowerShell. Here's an example using SharePoint Online PowerShell commands provided by Microsoft: 

// Connect to SharePoint Online
Connect-SPOService -Url https://contoso-admin.sharepoint.com

// Disable Social bar on pages at site level
Set-SPOSite -Identity https://contoso.sharepoint.com/sites/site1 -SocialBarOnSitePagesDisabled $true
