Hi @Ware
Per my knowledge, when you grant permission to an Active Directory group, the group will be added to the user information list but users in the group will not be added until they access the site collection.
We can grant permission to users then they will be added to user information list without login. There is no other workaround available in SharePoint.
You can use PowerShell Script to grant user permission or grant permission in site permission settings.
PowerShell codes:
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Parameters
$WebURL = "http:// "
$UserID="domain\user"
$PermissionLevel="read"
#Get the Web
$Web = Get-SPWeb $WebURL
$User = $web.EnsureUser($UserID)
#Grant Permission to User
Set-SPUser -Identity $User -Web $WebURL -AddPermissionLevel $PermissionLevel
