AEM trail version for EDS setup not showing the create site from template option

Try revisiting the EDS Cloud configuration on your environment.
You can try creating site from template after deleting the existing EDS cloud configuration,
That worked for me..

Hi ​@Kalyan_ChakravarthyCh 
Before deleting the existing EDS configuration or the DAM folder, please verify which setup flow you are using. For an AEM-authored Edge Delivery Services site, go to Sites -> Create -> Site from template and check whether AEM Site with Edge Delivery Services is available.

If it is not listed, the template may need to be imported/installed from the Import option. Also confirm that you have the required permissions and that your AEM trial environment is properly configured for the EDS/Universal Editor workflow.

If you are using the Cloud Manager flow instead, check Edge Delivery -> Create site now and select AEM Authoring with the correct author environment.

I would not recommend deleting the DAM folder as a first troubleshooting step, because it may contain site content or assets. Remove an existing configuration only after confirming that no active site depends on it and that the content has been backed up.
