Hi @Mark Gorelyk
Per my test, this code works for the form when you new items, for example, you could not find "Title" in the form after running the command:
Connect-PnPOnline -Url "https://crescent.sharepoint.com/sites/luyi"
Set-PnPField -List "test2" -Identity "Title" -Values @{Required=$False;Hidden=$True}
To hide the column in the view, you could use the command Set-PnPView, for example, when you use the command:
Set-PnPView -List "Documents" -Identity "Corporate Documents" -Fields "Title","Created"
You will get a view to show the coumn "Title" and "Created".
