Search box changes in modern SharePoint and OneDrive experiences

HI Kerem Yuceturk 

Is there a way we can push this to users as it will be really helpful with our new intranet page

some (2 or 3) users already have it and i have put our Sharepoint as to recieve preview features but dont want to put them on all office 365 early release really 

would be great if there was a powershell etc for this to be achieved

thanks
