Not sure if this is what you need but I saw something from the ITOM MicroFocus Marketplace:
There's a link above for "AWS deployment 2018.05"
I checked the AWS Marketplace and it still not available there. That's the one that I am interested in knowing the date when it will become available.
Hi - The AWS marketplace will be refreshed with the latest 2018.05 version within next 1-2 weeks. We are working on this activity with the AWS team.
