Creating SQL Server AWS AMI with Packer

I have been using packer with windows for many years.
I have used variety of provisioned including powershell provisioned.

I was recently asked to automate the provisioning of SQL Server 2019 on Windows Server 2019.
I am considering using DSC.
I will not be allowed to use DSC provisioned GitHub - mefellows/packer-dsc: DSC Provisioner for Packer.io

Has anyone used DSC with just PowerShell provisioner?
Has anyone successfully built a SQL Server AMI?
Should I be concerned about sysprep impact on SQL Server?

I am not asking for a solution just looking for validation that it is possible and any best practices or lessons learned.
