AWS FAQ:

Is Windows Server eligible for BYOL on EC2?

There are three requirements for Windows Server to be eligible for BYOL on EC2:

1. The licenses must be deployed on EC2 Dedicated Hosts.
2. The licenses must have been purchased before 10/1/2019 (or added as a true-up under an agreement that was effective prior to 10/1/2019).
3. The version was publicly available prior to 10/1/2019.

Software Assurance is not a requirement for Windows Server BYOL.
