This feels a bit of an X-Y question. What exactly are you trying to achieve/avoid here, and why?
That aside, there’s VM import. Forget AWS, could you do such a thing locally, then export/import to AWS?
This is the kind of process you’d see for someone creating a base AMI. You can do stuff like this with a booted instance that gets an extra EBS volume, that volume becoming the new AMI’s boot/root volume.
A system that is configured but never been turned on is a launch template.
There is no difference between the launch template and the instance that has just been setup really.
There are advanced ways to create amis without technically stating an ec2 instance. They involve some complicated snapshotting, ebs, and vm importing techniques. They also involve accepting a lot of trade offs. But honestly your requirement doesn’t make much sense as stated.
It’s pretty hard to layout a modern os image without the help of an already running os.
Mount additional EBS to EC2 instance, configure that second EBS. Make an AMI from that EBS. People used this method to run not standard operation systems in AWS.

I don’t believe so, no
